What happens in a buffer when the level of h+ ions in solution increases?

Buffer resist the change in pH of solution

Explanation:

Buffer : It minimize the change in pH due to addition of small amount of acid or base.

Buffer solution mostly consist of weak acid and its salt or weak base and its salt.

When H+ ion concentration is increases in the solution then conjugate base present in the solution consumed hydronium ion and it convert into water and weak  acid of conjugate base.Therefore, the result in decrease the amount of conjugate base and increase the amount of weak acid.

Buffer maintain the pH of solution.

When the level of H+ ions in the solution  increase then pH of the solution decreases then buffer maintain the stable pH of solution.

answer; i believe the correct answer is (replication is not conservative);
