NECO 2024 QUANTITATIVE ANALYSIS OF TETRAOXOSULPHATE (VI) ACID AND SODIUM TRIOXOCARBONATE (IV) SALT

Weldon sir. Good one

[@genesisdavid-ot5lk]

Just watching this boss this is a great work

[@minajames1435]

Wonderful job you do. Please, when you finish a titration, do you tap off the remaining acid in the tip of the burette since its not part of the burette calibration. I mean the added burette tip

[@ChemEasy_Eko]

No! The calibration of the burette typically includes the volume within the entire burette, including the tip. Therefore, any liquid remaining in the tip is part of the total volume dispensed as long as it was initially filled into the burette. You should not tap off or attempt to remove the remaining acid from the tip of the burette after the final reading. The volume that has been read from the burette scale includes the liquid in the tip as part of the burette calibration. Tapping off the remaining liquid would alter the actual volume dispensed, leading to inaccuracies in your titration result

Is it 5ml measuring cylinder or 10ml measuring cylinder

[@genesisdavid-ot5lk]

Good morning boss Please 🙏 What re the reagents used in the quantitative analysis between cuso4 and zn(no3)2. Have done it but i want to be sure if am correct 🙏.

[@ChemEasy_Eko]

Do you mean qualitative analysis?

[@genesisdavid-ot5lk]

@@ChemEasy_Eko yes sir the qualitative analysis

[@genesisdavid-ot5lk]

Good evening sir weldone sir Please how many ml is your measuring cylinder used to measure your acid of 3.8

[@ChemEasy_Eko]

10ml. But if u have 5ml measuring cylinder I ll advice you use it for more accuracy.

What if I did my titration ND d color does not changed, wat can be wrong with d titration?

[@ChemEasy_Eko]

So many factors could be responsible for it: 1. Check your indicator 2. Check the solutions concentration 3. Check the purity of the solution etc
