Two litres of 0.5 M `KMnO_4` solution have to be completely reduced in acidic medium. The number of Faradarys of electricity required will be

How acidified KMnO_4 solution reacts with the following in acidic medium : SO_2 .

How acidified KMnO_4 solution reacts with the following in acidic medium : H_2S .

A sample of 28 mL of H_(2) O_(2) (aq) solution required 10 mL of 0.1 M KMnO_(4) (aq) solution for complete reaction in acidic medium. What is the volume strength of H_(2)O_(2) ? X

4 mole of a mixture of Mohr's salt and Fe_2(SO_4)_3 requires 500mL of 1 M K_2Cr_2O_7 for complete oxidation in acidic medium. The mole % of the Mohr's salt in the mixture is :

A 3.4g sample of H_(2)O_(2) solution containing x%H_(2)O by mass requires xmL of a KMnO_(4) solution for complete oxidation under acidic conditions. The normality of KMnO_(4) solution is :

A mixture containing 0.05 mole of K_2Cr_2O_7 and 0.02 mole of KMnO_4 was treated with excess of KI in acidic madium. The librated iodine required 1.0L of NaS_2 O_3 solution for titration. Concentration of Na_2 S_2 O_3 solution was :

2.5 litre of 1 M NaOH solution are mixed and another 3 litre of 0.5 M NaOH solution. Then the molarity of the resulting solution is

A mixture of H_(2)SO_(4) and H_(2)C_(2)O_(4) (oxalic acid ) and some inert impurity weighing 3.185 g was dessolved in water and the solution made up to 1litre. 10 mL of this solution required 3 mL of 0.1 N NaOH for complete neutralization. In another experiment 100 mL of the same solution in hot condition required 4 mL of 0.02 M KMnO_(4) solution for complete reaction. The mass % of H_(2)SO_(4) in the mixture was:

0.1 M formic acid solution is titrated against 0.1 M NaOH solution. What would be the difference in pH between 1/5 and 4/5 stages of neutralization of acid?
