You can do that. Everyone in the hall can have the same end point but different values as initial and final. However, I will advise you to avoid using 0.00 as your initial all through except for the rough. Not only would it look like pure manipulations but almost every one will do that thereby creating suspicion for malpractice. Assuming for titration 1. Let your initial be 1.00, volume of A used be 20.30 (end point), then add the two to get final as 21.30 For titration 2 , assume your initial is 5.00 and volume of A used (end point) is 20.30, then final becomes 25.30. For titration 3, assuming the initial is 10.00 and volume of A is 20.30 (your end point) then Volume of A used is 30.30. You can take the initial of your rough as 0.00. Choose values randomly as your initial to build your table especially from 1 to 15. Don't use higher values as your initial to avoid having a final value above 50 because the burette capacity is 50.
If you are not given end point, start with number 2 and number 3. While solving them keep your ears open. The subject teacher will be in the hall. You will see him going round to inspect you guys. He will be frustrated on the kind of results he is seeing that he will give an idea of the end point to someone and you will capture it. If he says that end point lies between a range for instance 20.10 to 20.60. Then list all the values in this range on your rough work 20.10, 20.20, 20.30, 20.40, 20.50, 20.60 Cancel a value Infront and another at the back repeatedly until you reach the middle value and use it to prepare your table as the end point. In this case 20.30 and 20.40 are at the middle then choose any of them to prepare your table as the end point. Avoid cancellation of your table or altering figures because you will loose marks if you do so. However, if at the long run there is no end point given to you, then use ours
But 😢 I did it and I got my average volume of acid as 21.50😭 does it mean i will fail because in the report form the range of values were 20.40 20.60 and 20.80

We appreciate
Thank you very much Sir 🙏🏽🙏🏽🙏🏽God will bless you in abundance Amen🙏🏽

Thank you very much sir
God bless u for your great help👍
Thanks a lot
Thank you very very much sir!
You are welcome
Sir you will be highly favored in all your ways thank you😊
Thanks a million times
Thank you sir, but is it compulsory to leave all your answers apart from the table in 3 s.f .is it a most that your answers should be 3 s.f
Yes it is
Thank you sir
But we were told that the concentration should be in 3 decimal places sir
Very wrong. Concentration must be to three significant figures.
If God can bless a man, may he bless you sir❤
Amen🙏🏽
Amen. God bless you too.
Thank you so much for this
We appreciate
Thank you sir
God bless you 🙏
You are welcome
Thanks very much sir 🙏
You are the best ✊
You are welcome
You are welcome
Thank you sir but please I have a question,is the initial reading not supposed to be 0.00 in all.
Depends u can do that as well
You can do it like that too but just make sure you refill your burreteaftet each reading
You can do that. Everyone in the hall can have the same end point but different values as initial and final. However, I will advise you to avoid using 0.00 as your initial all through except for the rough. Not only would it look like pure manipulations but almost every one will do that thereby creating suspicion for malpractice.

For titration 3, assuming the initial is 10.00 and volume of A is 20.30 (your end point) then Volume of A used is 30.30.
You can take the initial of your rough as 0.00.
Choose values randomly as your initial to build your table especially from 1 to 15. Don't use higher values as your initial to avoid having a final value above 50 because the burette capacity is 50.
Thank you very very much sir

Thanks a lot sir❤❤❤❤❤

Thanks sir but what if my school doesn't give us end point can I use yours

thanks nice one
Thanks
Thank you sir ❤❤❤
You are welcome
Thanks sir
You are welcome
Is it a must that we use our teachers reading coz in my school the teachers don't give us their reading
They would still give you a reading. It's their duty.
But if we use this mans own it's okay right?
But if we use this mans own it's okay right?
Use your teacher's end point. If he doesn't give you on time, start with number 2 and 3, he will most likely say it in the hall
Thanks sir. But I have a question, d specification given in d specimen list was 6g of Na2co3, hope it won’t affect the readings
Not at all
Where's the calcium ion coming from please? I thought D is solution of powdered milk.
@@kelechiezeorah4619where did u see calcium?
@@Footballites check where you described miller test. You mentioned calcium salt which wasn't given.
My confusion is calcium
wahh gwan
Yes
Thanks but how legitimate 🙏
It's legit
Its real
We have a name
Are those the actual questions??
@@Riley-p2t yes they are
Is this legitimate
Stay there and be asking questions
