Answer:
Solution A has the greater concentration of hydronium ions. That solution is 100 times more concentrated than the other solution.
Explanation:
For solution A take 10^-pH in this case 10^-2=.01
For solution B you would take 10^-4=.0001
.01>.0001 so solution A is more concentrated with H^+
To figure out how much more concentrated one solution is than the other:
(10^-2)/(10^-4)
The Answer to your question is Erosion I Learned It Last Year.
There are so many examples for that in different areas, like SF34 experiment carried out in our lab recently.Here's one link: http://www.alfa-chemistry.com/sf34-cas-1799329-54-6-item-294465.htm
