Question

Give an example acidic and basic buffer and give their action

Answer 1

Acidic buffer solution contains equimolar quantities of a weak acid and its salt with strong base.

Answer 2

What is buffer action?

Buffer action is the ability of a buffer to resist a change in the pH value when a small amount of acid or base is added to that solution.

Buffer action of acidic buffers :-

In a aqueous solution, the acid being a weak electrolyte gets ionised to a small extent while it's salt gets completely ionised being a strong electrolyte.

Buffer action of basic buffers :-

In a aqueous solution, the base is ionised to a small extent as it is weak electrolyte while it's salt is almost completely ionised as it is strong electrolyte.
