Question

The volume of 0.2N feso4 required to reduce 0.01 equivalent of KMnO4 in acid medium is?

Answer 1

start of with chemical reaction equation

Answer 2

2Kmno4 + 8 H2so4 + 10 feso4 -> k2so4 + Mnso4 + 5fe2(so4)3 + 8h2o

Answer 3

where did you get that H2SO4? it says acidic medium as i see...

Answer 4

In acidic medium so..

Answer 5

so write equation again without H2SO4

Answer 6

Why??? we have to acid right.

Answer 7

oh god, im toooo tired for this... plead to somebody else to help you

Answer 8

@Preetha plz help

Answer 9

I am sorry. I am so confused. I assumed you would use mass/volume formula after balancing.

Answer 10

@siddhantsharan

Answer 11

By law of equivilants,
Equiv. of feso4 = equiv. of Kmno4.
V * 0.2N = 0.01
Therefore V = 0.2/0.01 = 20litres.
