Question

the volume of 0.05 K2Cr2O7 solution which can oxidise 200ml of 0.1M FeSO4 solution in acidic medium is​

Answer 1

Answer:

400ml

Explanation:

Data

V1 of k2CrO7 =?

M1 of K2CRO7 = 0.05

V2 of FeSO4 = 200

M2 of FeSO4 = 0.1

formula M1V1 = M2V2

0.05 multiply V1 = 0.1 multiply 200

0.05 multiply V1 = 20

V1 = 20/0.05

V1 of K2CRO7 = 400ml
