Answer :
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).
