`{:(CH_(2)COOH),(|),(C(OH)COOH),(|),(CH_(2)COOH) :}

Options

A. When behaves as reducing agent, then its equivalent weights are equal to half of its molecular weight respectively
B. `1000mL` of 1N solution of each is neutralized by `1000mL 1NCa(OH)_(2)`
C. `1000mL` of `1M` solution is neutralized by `1000mL` of `1M Ca(OH)_(2)`
D. `1000mL` of 1M solution is neutralized by `200mL 2M` of `KMnO_(4)` in acidic medium.

Answer

A, B, D

Explanation

For `{:(underset(|)COOH),(COOH):}` & `{:(underset(|)COOK),(COOH):}`
When behave as reducing agent
`(COOH)_(2) rarr 2CO_(2)`n-factor `=2`, eq wt. `=M//2`
`{:(underset(|)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`
