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
\(pH = -Log[H^+]\)
so here we know that pH of the solution is decreased by 2
so we have
\(pH_1 - pH_2 = 2\)
now using above formula
\(2 = -Log[H_1^+] + Log[H_2^+]\)
so we will have
\(Log\frac{H_2^+}{H_1^+} = 2\)
\(\frac{H_2^+}{H_1^+} = 10^2\)
so hydronium ion concentration will decrease by factor of 100
