<< < (5/347) > >>

Uchia:
lol ok my apologies

Meticulous:
I need help with this question:

" 25 cm3 of potassium iodate (V) solution was added to excess potassium iodide solution. The iodine liberated required 30 cm3 of 0.5 mol dm-3 sodium thiosulphate. Calculate the concentration of the potassium iodate (V) solution."

Needed ASAP.

Thanks in advance.

Uchia:
at least give us the equation is that cie or edexcel

Meticulous:
The topic says it's Edexcel, and so it is. It' not a past paper. And there's no equation. Just the way it is. Just a normal thiosulfate titration.

Meticulous:
Got it now.
