Question

A soltuion contains mixture of `H_(2)SO_(4)` and `H_(2)C_(2)O_(4), 25mL` of `N//10 NaOH` for neutralization and `23.45 mL` fo `N//10 KMnO_(4)` for oxisation. Calcualte:
(i) Normality of `H_(2)C_(2) O_(4)` and `H_(2)SO_(4)`
(ii) Strength of `H_(2)C_(2)O_(4)` and `H_(2)SO_(4)`.
Assume molecular weight of `H_(2)C_(2)O_(4) = 126`

Answer 1

Correct Answer - (i) `H_(2)C_(2)O = 0.0938N, H_(2)SO_(4) = 0.0482N`,
(ii) `H_(2)SO_(4) = 2.362g//"litre"`
