But, why are you cancelling the rough titre. You don't need to cancel your table at all. Since you didn't use it in your averaging. You might be pardoned. But please stop that
0.00 is usually used if you have to refill the burette after every titration... otherwise your initial should be where your previous titration stoped... But the best is 0.00 since it is easier to calculate
It's very interesting and educative, but I want to ask this question" when talking our reading from the burette,, that it must end with a 5 or 0 but not 12346789. Eg. 18.20 not 18.21 or 18.25 not 18.23. how true is this
Please, your burette readings must always end with 0. Because the least amount of volume measure able on burette is 0.1. So the second decimal must be zero
But sir during your explanation you said if one's value is different from the teachers by 0.15 is still ok and let for example my teacher is 18.20 and mine is 18.35 am till correct based on your explanation in the video but you now sad must end with zero so am confused please sir
Yes, it is even the best. When your Titre value is absolutely the same with that of your teacher. Because, you both used the same chemicals, under the same conditions and at the same time. So all things been equal, you are to get the same titre values
Thanks for sharing. But why can't waec body educate students on this?
Honestly, WAEC is just a body, it is we Teachers that we are supposed to be sensitizing students on it.
But we are very few marking WAEC.
And if you are not marking, you can't understand the deductions even as a teacher.
Hmmm, this is so sad. We are really suffering 😢😢
Brilliant explanation
❤❤❤ thank you so much sir may God increase your strength 🙏 and knowledge inshallah 🙏🙏🙏🙏
Amen
Thanks for sharing
You are welcome
This is very insightful and eye opening. ❤❤
Please sir can you give us examples on how it is meant to be, like clear examples.
God bless you sir..the best video I have seen so far
You are Always welcome.
Good one
Thanks so much
Thank you sir, for leading us right 👍
You are always welcome
Thank you very much for this
It's my pleasure
Thank you sir for making this video. I never knew about some of these rules but now I know
You are welcome.
Thank you so much sir.
You are most welcome, more videos are still coming that will unleash a lot of secrets
❤ thanks sir
You are welcome
what if you shade or cross in qualitative analysis
There is no penalties for shading or crossing in qualitative analysis
What if you cancel your answer when solving the follow up questions due to some blunder
There is no problems, once you didn't cancel the Table.
Thank you sir
This happened to me during the exam I undertook yesterday. But I’m now pleased.
Sir, is there deduction of marks for cancellation of the rough titration
But, why are you cancelling the rough titre. You don't need to cancel your table at all.
Since you didn't use it in your averaging. You might be pardoned. But please stop that
Thanks sir noted sir
Well done sir.
yesterday, some students use the molar mass of FeSO4 which is 152g rather than 56g( just for iron). Are they wrong?
They're wrong
Yes
Sir please explain futher when you said initial rading would be 0.00 . That woud be the number eleven
0.00 is usually used if you have to refill the burette after every titration... otherwise your initial should be where your previous titration stoped...
But the best is 0.00 since it is easier to calculate
Thank youuu sir
Do you have for physics sir
I will also do videos on physics very soon.
If you cross multiple and it doesn't reach the formula does that means you have failed it
No, once you don't cross any of what you have written. You will still get your mark. Intact.
Sir, so if you use pencil to draw your table waec would still remove marks .
No, only if you write in Pencil.
Thank you Sir.. 🙌
But there's a video like this,
Though, u went dipper...
You are most welcome, more quality videos to come. Until you people succeed, I won't stop.
Success in your Ways.
Please is the any penalty for cancelling the qualitative analysis table
There's no penalty for that. But there are also other penalties for qualitative analysis.
Thank you
Sir I forgot to indicate my volume of Pipette how many marks do I loose .... I'm so scared
you will probably lose one mark. it's not really much
Ahh🙆🙆 i never knew some of this, but sir concerning the construction of table is the table not already in the work sheet🤷🤷
Sir how Will WAEC know that Alkali is in the burette
Sir, if you have 18.60 as final and initial value is it wrong
Yes, some times, it has been drawn for you, but you must not write in Pencil. Or cancel what you have written.
@@timothyadepoju8763 WAEC will Know, when you mistakenly substitute base for acid in your formula.
@@timothyadepoju8763 If you add 18.60 to 18.60 it equals 37.2. since it is not up to 50. Which is the maximum value of the burette, it is acceptable.
I am watching this late! My teacher's value was 17.9 and i got 17.4
Heyah, so sorry. There is still hope
@@Solubletutors amen sir
Must titre value be the same with my teachers own?
IT must not be too far from the teacher's Titre value, just has I've explained in the video
As I've explained in the video
It's very interesting and educative, but I want to ask this question" when talking our reading from the burette,, that it must end with a 5 or 0 but not 12346789. Eg. 18.20 not 18.21 or 18.25 not 18.23. how true is this
Please, your burette readings must always end with 0. Because the least amount of volume measure able on burette is 0.1. So the second decimal must be zero
Thank you sir. So it shouldn't even end with 5?
@@aondoaseerstephen6138 no, it must end with zero.
@@Solubletutors thanks sir
But sir during your explanation you said if one's value is different from the teachers by 0.15 is still ok and let for example my teacher is 18.20 and mine is 18.35 am till correct based on your explanation in the video but you now sad must end with zero so am confused please sir
Wow😮😮😮😮
Sir is it possible that your teacher titre value must be the same with yours
Yes, it is even the best. When your Titre value is absolutely the same with that of your teacher. Because, you both used the same chemicals, under the same conditions and at the same time.
So all things been equal, you are to get the same titre values
@@Solubletutors ok thank you sir
@@EipegaSamuel-vq4lq Hope you have subscribed and shared to people
In yesterday calculation of g/dm³, molar mass of FeSO4 was used instead of just for iron. Will the students receive any mark for that?
@@Uncle-Chemical No, Since the question specifically asked for Iron. Atomic mass of Iron was expected to be used.
