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.

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

When a buffer solution of CH_(3)COOH and CH_(3)COONa is diluted with water

When CH_(3)COONa is added to an aqueous solution of CH_(3)COOH

In CH_3COOH/CH_3COONa buffer, the reserve acidity is due to

The pH of a buffer solution containing 25 ml of 1 M CH_(3)COONa " and 1 M " CH_(3)COOH will be appreciably affected by

The pH of a buffer solution containing 25 ml of 1 M CH_(3)COONa " and 1 M " CH_(3)COOH will be appreciably affected by

Assertion (A): The pH of an aqueous solution of CH_(3)COOH remains unchanged on the addition of CH_(3)COONa . Reason (R) : The pH of an aqueous solution of CH_(3)COOH remains unchanged on the addition of CH_(3)COONa . Reason (R) : The ionisation of CH_(3)COOH is supressed by the addition of CH_(3)COONa .
