underset(COOH)overset(COOH)(|) and underset(COOH)overset(COOK)(I) behave is acids as well as reduing agents. Then which of the following are correct statements?

Answer»

When behaves as reducing agent, then its equivalent weights are EQUAL to HALF of its MOLECULAR weight respectively
1000 ml of 1N SOLUTION of each is neutralized by 1000 mL 1N `CA(OH)_2`
1000 mL of 1M solution is neutralized by 1000 mL of IM `Ca(OH)_2`
1000 mL of 1M solution is neutralized by 200 mL 2M of `KMnO_4`in acidic medium.

Solution :For `{:(COOH),(|),(COOH):}&{:(COOK),(|),(COOH):}`when behve as reducing agent `(COOH)_2 rarr2CO_2` n - factor = 2, eq wt. `M//2 {:(COOK),(|),(COOH):} rarr 2CO_2` n - factor = 2, eq wt. = M/2 for neutralization meq of one reactant = meq of other reactant can be neutralized `1000 xx 2 = 1000 xx 2 `
