Question

Explaijn the action of acidic buffer

Answer 1

An acidic buffer solution is simply one which has a pH less than 7. Acidic buffer solutions are commonly made from a weak acid and one of its salts - often a sodium salt.
 A buffer is a solution containing a weak acid and its conjugate base in similar amounts. This combination reduces the pH change upon addition of strong acid or base by converting H1+ (or OH1-) to weaker acids or bases.
