Question

question 10
the function of a buffer is to ________.
o increase the ph of a solution.
minimize changes in ph by absorbing or releasing h+ in a solution and consequently stabilize the ph of the solution.
o decrease the ph of a solution.
o slow down chemical reactions.

Explanation:

Buffers are solutions that resist pH - changes. They contain a weak acid - conjugate base or weak base - conjugate acid pair. When an acid or base is added to the buffer solution, the buffer components react with the added acid or base to minimize the change in pH by absorbing or releasing hydrogen ions ($H^+$).

Answer:

minimize changes in pH by absorbing or releasing H+ in a solution and consequently stabilize the pH of the solution.
