Do you need more videos? I have a complete online course with way more content.Click here: purchase.kevin... 🟢Follow me on Instagram: / kevinmathscience
Thank you Kevin!
Much love from the matric class of 2024.
You are truly a hero for providing your help and teaching skills here on youtube for free.
You are as selfless as they get!
I am writing a test tomorrow on this topic and nobody i mean nobody explained this better than you thank you Kevin you've gained a new subscriber and a viewer❤
I'm writing P2 on Monday it's the first time I'm understanding acid and bases😭thank you Kevin
Same 😭
@@spike5473 good luck for Monday😭🫂
Same😂
@@JabulaniXango today is the day😂
Eish um writing in 2 hours🤧
Weeks before prelims and im finally getting to learn something i was meant to have known for my june exams . Thank you kevin . I took your advice , went back to the grade 11 videos before coming to complete the grade 12 playlist . I understsnd this so much better ! Youre my hero , once again
you are a lifesaver. please continue to bless us
Shoutout to his ex , his a lifesaver - Drake ( IDGAF )
hey Kevin can you please make videos more focused on the multiple choice questions for P2. Thanks in advance
Finally someone i can understand...thank you for this chapter really needed help❤💯
You're welcome!
Thank You💕, I've been waiting for you to finally do this chapter.
You're welcome Tshiamo😊
This man is the love of my life
I passed my matric bcz of this man ,he best.
My teacher actually use this formula for the OH ph. It follows such as: ph(OH)= 14 - ph(hydronium ions). I think it's a 100 times easier and i just wanted to share it with you. 😊
Hi Nizam, I have seen that in textbooks and you are correct! It is actually a super awesome formula. Easy to understand :)
All the best!
The funniest thing is i love chemistry, physics?? Not so much 😂
same 😂
@@BrendonThabisoChiwota we're doing electrostatics rn and I kinda like it. Ask me again in 3 weeks how I feel about physics
3 hours before exam 2022 matric 😉
same fr fr😭
The pressure 😂😂
Bro 😂🙆🏿♀️
Bruhh few minutes 😭✋
5 hours and 30 minutes until we write our nsc physics paper 2🤐
It appears you and I are not sleeping
@@Sapphire_Stallion mee tooo😢
@@Sapphire_Stallion honeslty. last physics paper so we have to push
Another way of finding for the pH of a 4dm³ solution containing 3 mol NaOH :
CoH = n ÷ v
= 3 ÷ 4
= 0,75 mol/dm³
pOH = -Log[ OH‐]
= -Log[ 0,75 ]
= 0,125
pH + pOH = 14
pH + 0,125 = 14
pH = 14 - 0,125
= 13, 875
Proof = 13,875 + 0,125
=14
From a grade 11 student, xoxo .💋💋💋
I'm in grade 11 but I have to learn this for me test 😪 thank you sm!! the video really helped
Glad it helped you!
Congratulations on 100k🎉
You are the best.. now I got a clue of what's going with acid and bases ... I can't believe it🙂
Sorry I have a problem, isn't Kw equal 1.0-¹⁴ instead of 10-¹⁴?
Wow youre so good, i was clueless😭😭😭💘
Happy to help!😁
Grade 11 but already doing this😭😭
since the ratio for HCL and H30+ is 1:1
and ch3chooh and h30+ is also 1:1
if it is given that hcl and ch3cooh have same concentration
Would that mean they have same ph?
Hey kevin,may you please share a link for the grade 11 Acids and Bases because i can't seem to find them😭
Kev, if they don't say that we should assume that H2SO4 is diprotic, would it just ionise to HSO4 minus?
thank you sooooooo much i now finally understand how to calculate PH🥺
Thanks!
I only saw this now! Thank you so much!!!! :)
you are literally sent from God!
Hii, does the subscript of the hydrogen/hydroxide always determine the ratio??❤
You make things so easy
Hey Kevin l, love your videos can you please do some titration examples
Hello :) Will do my best but cannot promise exactly when!
As'bonge Mnr Kevin🙏🏾
Hy Kevin on the number of moles we got for Hydronium ion shouldn't we use a balanced formula to know moles for Hydrochloric acid then find the mass?
I'm writing tomorrow 😮
Hey Kevin I have a problem on the one of determine the pH of a 3dm3 container with 1 mol of mg(OH)2 my answer is 11,82 please help
Can you treat question papers🙏🏿
Especially that 8 mark question 🙏🏿in acid and bases
Will do my best! :)
@@kevinmathscience will be appreciated
Thank you Kevin
Thanks Kevin
No problem 👍
1 hour before the final exam 😆 u know the drill... matric 2022
Thank you 🙏♥️
Thank you sir❤
10:23 shouldn't we divide by ⅔?
Hello Smiley, yes that is exactly what I did in that step :)
Bra he did divide he just didn't show us;he probably thought the learners will understand what happened since they are in grade 12

Thank you❤❤
hi kevin.
do you have a playlist for this chapter (acids and bases)?
Yes for grade 12 acids bases here:
th-cam.com/play/PLU_DCVXL8MyO5m6Uuu9pur6zRFYpDZCe2.html
kevin do you have grade 11 acids and bases, I cannot find it in your playlists
Kevin how do I identify acid and base .. how can I see if I'm dealing with a base or acid
You must just go through your textbook and note down the common acids and bases :)
I'm in grade 11😅, and I'm writing on this Sunday
I love this teacher lol, he is the best 😍😍
Can't find the grade 11 work can u send a link.
Light work🤌
logs whuu🤣
