The ph of a solution decreases by 2.0. how does the hydronium ion concentration of the solution change?

hydronium ion concentration will decrease by factor of 100

Explanation:

As we know that form to find pH of the solution is given as

so here we know that pH of the solution is decreased by 2

so we have

now using above formula

so we will have

so hydronium ion concentration will decrease by factor of 100
