A solution with pH 4 has __________ the H⁺ concentration of a solution with pH 8.

Question

Quizplus · Accepted Answer

The pH scale is a logarithmic scale, meaning that every change of 1 in pH corresponds to a tenfold change in hydrogen ion concentration. Therefore, a solution with pH 4 has 10,000 times more hydrogen ions (H+) than a solution with pH 8. Since H⁺ is acidic, its concentration will decrease as the pH increases. Therefore, the solution with pH 4 has a concentration of H⁺ that is 10,000 times lower than the solution with pH 8. Thus, the answer is D: 10,000 times.

A Solution with PH 4 Has __________ the H+ Concentration
