Always. You never know what kind of chemical you’re dealing with and how powerful it is.
Answer:
The correct answer is "A buffer resists pH change by neutralizing added acids and bases".
Explanation:
In chemistry, a buffer is defined as an aquoeous solution that resist pH changes. Buffers are comprised of a weak acid (HA) and its conjugate base (A−) in an equilibrium relation, which results in the buffer neutralizing added acids and bases. Buffers play a crucial role in living beings since they provide a relative stable environment for the cells in what is known as homeostasis.
