A solution with a pH of 2.0 has a hydronium ion concentration ten times greater than a solution with a pH of
(1) 1.0 (3) 3.0
(2) 0.20 (4) 20.

The answer is (3) 3.0. The solution with a pH of 2.0 has greater concentration means the other solution has greater pH. pH=-lg[H+]. So we can get the pH of other solution is 3.

Answer:The correct answer is (3).

Explanation:

The pH of the solution is defined as negative logarithm of [tex]H^+[/tex] or hydronium ions ions in the solution.

[tex]pH=-\log[H^+][/tex]

[tex]2=-\log[H^+][/tex]

[tex][H^+]=0.01 M[/tex]

The pH with 10 times the concentration [tex]H^+[/tex] ions.

[tex][H^+]=10\times [H^+]'[/tex]

[tex]pH=-\log[H^+]'=-\log[\frac{0.01}{10}]=3[/tex]

Hence, the correct answer is (3).
