Question

Which statement is true?

A. A solution with a pH of 6 has 100 times as many OH- as a solution with a pH of 8.

B. A solution with a pH of 6 has 10 times as many OH- as a solution with a pH of 8.

C. A solution with a pH of 6 has 100 times as many H+ as a solution with a pH of 8.

D. A solution with a pH of 6 has 20 times as many H+ as a solution with a pH of 8.

Answer 1

A solution with a pH of 6 has 10 times as many H+ ions as a solution with a pH of 8.

Step-by-step explanation:

pH is a logarithmic scale. A solution that has a pH of 6.0 will have 10 times as many H+ ions as a solution with a pH of 7.0. So, the statement 'A solution with a pH of 6 has 10 times as many H+ ions as a solution with a pH of 8' is true, making option B the correct answer.
