When `2mol` of `HCI` is added to `1L` of an acidic buffer, its `pH` changes from `3.4` to `2.9`. The buffer capacity of the buffer solution is

When 0.01 moles of sodium hydroxide are added to a buffer solution, its pH changes from 4.745 to 4.815. The buffer capacity of the buffer solution is :

When 2 mols of HCl were added to 1L of a certain acidic buffer, the pH of the buffer decreased from 4.4 to 3.9. The buffer capacity of this buffer solution is

When 0.02 mole of an alkali is added to an acid buffer , the pH changes from 4.75 to 4.8 the buffer capacity is

Buffer capacity of acid buffer solution is more when
