Answer:
hydronium ion concentration will decrease by factor of 100
Explanation:
As we know that form to find pH of the solution is given as
[tex]pH = -Log[H^+][/tex]
so here we know that pH of the solution is decreased by 2
so we have
[tex]pH_1 - pH_2 = 2[/tex]
now using above formula
[tex]2 = -Log[H_1^+] + Log[H_2^+][/tex]
so we will have
[tex]Log\frac{H_2^+}{H_1^+} = 2[/tex]
[tex]\frac{H_2^+}{H_1^+} = 10^2[/tex]
so hydronium ion concentration will decrease by factor of 100
