Question

Quizplus · Accepted Answer

An acid-base indicator is a compound that changes color in response to changes in the pH of a solution. When placed into an acidic or basic solution, the indicator undergoes a change in its chemical structure that causes it to change color. Examples of acid-base indicators include phenolphthalein, bromothymol blue, and litmus. Amphiprotic compounds can act as both an acid and a base, but they may not necessarily change color in response to changes in pH. Buffers are solutions that resist changes in pH, while protonated compounds have gained a proton.
