Which of following aqueous mixture of `CH_(3)COOH` and `CH_(3)COONa` will have maximum buffer capacity?

A

`[CH_(3)COOH] = 1M, [CH_(3)COONa] = 10^(-3)M`

B

`[CH_(3)COOH] = 0.1 M, [CH_(3)COONa] = 10^(-5)M`

C

`[CH_(3)COOH] = 0.1 M, [CH_(3)COONa] = 0.1 M`

D

`[CH_(3)COOH] = 0.001M, [CH_(3)COONa] = 0.1 M`

Assertion (A): On mixing equal volumes of 1M Hci and 2 M CH_(3)COONa , an acidic buffer solution is formed. Reason (R) : The resultant mixture contains CH_(3)COOH and CH_(3)COONa which are parts of acidic buffer.

Assertion : Mixture of CH_(3)COOH and CH_(3)COONH_(4) is an example of acidic buffer. Reason : Acidic buffer contains equimolar mixture of weak acid and its salt with weak base.
