What happens in a buffer when the level of H+ ions in solution increases? It accepts OH– ions. It accepts H+ ions. It donates H+ ions. It destroys OH– ions.

There are two kinds of buffer

a) acidic buffer

b) basic buffer

They both resist change in pH on addition of small amount of strong acid or base

as asked in question we will consider addition strong acid that is [H+]

a) acidic buffer: it is a mixture of weak acid and its salt with strong base

say CH3COOH + CH3COO-Na+

When we add H+, the H+ are being consumed by acetate ions to give acetic acid

CH3COO- + H+ ---> CH3COOH

So it accepts H+

b)basic buffer

Example: NH4OH + NH4Cl

when we add H+ , the OH- will react with it to form water

So it accepts H+
