Question

A(n) ________ can be defined as a substance that prevents the ph of a solution from changing by either releasing or absorbing h+ in a solution

Answer 1

Step-by-step explanation:

When an acid or base is added to a solution then any resistance by the solution in changing the pH of the solution is known as a buffer.

This is because a buffer has the ability to not get affected by the addition of small amounts of an acid or a base. As a result, it helps in maintaining the pH of the solution.

Thus, we can conclude that a buffer can be defined as a substance that prevents the pH of a solution from changing by either releasing or absorbing
`H^(+)` in a solution.

Answer 2

A buffer can be defined as a substance that prevents the pH of a solution from changing by either releasing or absorbing H⁺ in a solution.
Buffer is a solution that can resist pH change upon the addition of an acidic or basic components and it is able to neutralize small amounts of added acid or base, pH of the solution is relatively stable.
