Redox Titration(WAEC 2024)CHEMISTRY PRACTICAL PREP.Acidified KMnO4 and Iron(ii) sulphate. FeSO4

Titration between Potassium tetraoxomanganate(VII) and Iron(ii) tetraoxosulphate(VI) under acidic medium of dilute tetraoxosulphate (VI) acid. The possible questions and the laid down procedure to get accurate end point. How to detect the correct color change at endpoint.

Please it's about the Chemistry practical on YouTube, about KMno4 and FeSO4.

I noticed that your end point is within 22.50 - 22.70cm³. I used my dad's lab. reagents and I was getting 38.00cm³, and 40s.

I was wondering what was the quantity of solution A and B you used/weighed out?

Please I also want to understand.

For instance, If you are to prepare 200cm³ solution of 5.5g FeSO4 per dm³.
# Are you going to weigh out the exact 5.5g and add water to mark 200cm³.
OR
# Are you going to calculate the mass of the FeSO4 (like m= mass conc x x 0.2dm³). Then weigh out the mass and add water to mark 200cm³?

How do you know the concentration and volume of sulphuric acid needed to protonate the medium?

[hemagamal]

What is the colour of kMnO4 in neutral and basic medium during titration?

[johnnwachukwu]

How do one know the vol, of acid to be used to acidify the iron

[MondayGodwin-ntpx]

How do you prepare 2M solution of sulphuric acid?

Please sir can you solve the last question on the possible questions that you said may come out?

[AdunniBello-Marwan]

Is it necessary to top up the oxidizing agent in the burette while titrating?

[ezebuilochioma]

Sir is any indicator in this titration

[chyzontrix]

Sir is Iron ii sulfate the Acid or Base ? 🤲

Is this really for 2023 coz that's what I am watching this for
