This account is actually amazing. In my year 10 exams, with your help I managed to get a 6 in biology TRIPLE HIGHER with your help! Currently revising for my year 11 mocks in November. You deserve more credit. Thank you so much.
Imagine, in school you learn how to do a titration from the experiment taking roughly 10-15 mins. And you can simply learn it with free science lessons for frickin 3-4 mins
my teacher for chem just explains it in a long way which takes 1 hour cause he does the practical. I made notes but I don't understand them, this guy taught me quickly and now i understand.
If possible could you please do a level videos as I'm struggling with them when I struggled with GCSE chemistry I used your videos and did really well, if you aren't going to do a level videos can you recommend any chemistry a level TH-cam channels as I struggle to find useful ones? Thanks
I distinctly remember getting a grade 8 on my Chemistry synoptic last year ago in a test when I was at the start of Year 10. Guess what? It was because of Sir FreeScienceLessons!!
the two volumes 0.1 apart, that's called concordant results if a question comes up it will say what concordant results are just remember to discard anomalies when a calculating mean
Thanks for the video sir. I'm currently doing my IGCSE and although these videos are meant for GCSE, there are some useful stuff which are common with IGCSE. Is it possible to have a "Ask a question" section in your website where we can ask questions to you? Thanks a lot.
if methyl orange is red in an acid, how come the solution is neutral once we add enough and it is red. surely that means the solution is acidic now, not neutral?
Thank you for the amazing video I was asking if there was a video you made about how to prepare solube salts by the reaction of an acid and alkali by titration method. I think (if I'm not wrong) this video explains neutralisation, but not the preparation of a solube salt. Kindly, is there a video for this requested topic? Thanks in advance. 😊
Hi, I was wondering if I will loose marks if I write the chemical formula for the indicators instead of writing the name in my exam, eg C20H14O4 for phenophthalaein ?
With a titration reaction, you don't really have an independent and dependent variable as such. You are trying to determine the concentration of an acid or alkali so that would be the dependent variable (in a sense). Control variables could be the number of drops of indicator, the known concentration of acid (or alkali), the starting volume of unknown acid or alkali and ideally the temperature of the room.
Thank you sir for the amazing videos! are you planning to do any other videos for other subjects such as math because that would be AMAZING!! and can you give me any advise for gcse biology (b1,b2,b3) because i am really worried
Control variables would be things like the initial concentration and volume of sodium hydroxide, temperature of the room, amount of indicator added, etc.. Everything that should stay the same when you repeat the test. I'd say that dependent variable would be the colour change, independent would be the amount of acid added? I could be wrong on that though.
when will you be releasing biology and physics paper 2 as i need to finish my notes asap. this years gcses are in like 5 months. thanks for all the amazing videos so far. have all been extremely concise
Generally a titration produces a soluble salt. An insoluble salt would produce a precipitate which would interfere with the colour of the indicator. However, there are titrations that do produce an insoluble salt but they're more for A level.

THANK YOU SO MUCH, taking my chemistry exam tomorrow and the videos have been lifesaving.
I like the fact that in every video, u stand in the same stance lol and ur stuff is informative by the way, thanks
Would you be able to do videos on A level sciences?
Watching these on the morning of my exam. Wish me luck 🙏
THANK YOU this practical has been haunting me in my nightmares so THANK YOU FOR EXPLAINING IT.

got a 9/9 thanks to u! revising this for alevel test tomorrow! please tell me u will be doing OCR a level chem and bio!

Hello Sir, just wanted to ask, which practical do you think is most likely to come up on the chemistry paper 1 for AQA Higher in 2 days time?
titration if your triple and proberably energy changes practical due to it not coming up any other years so far
revise everything
i think its gonna be this titration probably wont be the salt crystal one
Covers By Riya titration or soluble salts as others have already come up
This one
I distinctly remember getting a grade 8 on my Chemistry synoptic last year ago in a test when I was at the start of Year 10. Guess what? It was because of Sir FreeScienceLessons!!
Why does the liquid curve at the top forming a meniscus? Why is it not just flat?
I want to know too
Water molecules are more attracted to glass than to each other. This causes them to climb the sides of the glass, forming a meniscus.
@@Freesciencelessons ah, I see. Thank you - much appreciated.
Thnx so much for ur amazing videos! Idk why I didn't just watch these during lock down.
Paper 1 tommorow
We're done for
its not looking good bruv
11 hours left
Hi, when calculating the mean titration value is it the mean of the two volumes 0.1 apart or the mean of all recorded values. Thank you.
the two volumes 0.1 apart, that's called concordant results
if a question comes up it will say what concordant results are just remember to discard anomalies when a calculating mean

Thank you! You are actually amazing
what would happen if the acid was in the conical flask. what indicator would you use?
May I please know the independent, dependent and control variable for the titration reactions, thanks a lot.

Control variables could be the number of drops of indicator, the known concentration of acid (or alkali), the starting volume of unknown acid or alkali and ideally the temperature of the room.

@@n0brainjustvibes I'm pretty sure it's the amount of acid is what u measure(dependant) and I think the acid or alkaline is the independent variable

Free Science lessons you teach us practical lessons very well . Sir are you an English
Should i use a soluble base?
Saved My life once again
exam tomorrow, you are my hero
last min revision for tomorrow setting myself up for failure
What are the variables for this practical
Good luck for chemistry paper tomorrow!!!!!😭😭
Sir when we look at the miniscus at eye level if we do not do this is it called parralex error?
I recommended this video to my class mate and he said something about you being an anime character (something related to anime like them japanese)

Thank you so much!!
where is the revision workbook?
i hope i pass this test this means a lot to me i cant risk losing wish me luck i have 2 days left....:3
good luck lol
how did it go?
does anyone know if i am able to do sciences at A-level eventhough i got a b in science core last year?
sir I don't see titration as a required practical for aqa combined science, is this for triple or something?
Hi. Yes this is for triple. I've now added "triple" into the name to avoid confusion.
good luck today :)
I'm trying to find your workbooks but there is no link above. Where is it?

i love ur suit and tie
Hi free science lessons
he clearly likes it!
Which practical is most likely to come up?
Will your revision workbook be out in time for current year 10's before their exams
ah shit here we go again 2021 wya ?
i love you sir
You are an amazing man
sir when it says " concordant results" will it always be the volumes within 0.1dm3 of each other or can it it be different in the exam?
Does this make soluble or insoluble salt
Generally a titration produces a soluble salt. An insoluble salt would produce a precipitate which would interfere with the colour of the indicator. However, there are titrations that do produce an insoluble salt but they're more for A level.
Is this practical required for the higher trilogy paper for the current 2018 band?
No this is only for students studying triple Chemistry, not trilogy.
Freesciencelessons Okay, thank you for replying. My class has a lot of gaps in our learning, and your videos really do help, so thank you. :)
got chem paper 1 tmr morning and I started revising now (8pm) im so cooked
Who is here the morning of the exam 🤩🤩
Sir would a titration be a 4 marker in the exam or a 6 marker?
It's usually a 6 marker in the exam but it can be 4 marks if they already give you some of the beginning steps.
Thanks mate your a legend
Thanks very much. I appreciate your comment.
The way he formally replies to informal comments just surprises me
hey sir could you please start teaching A level science next year
