When the PH is 7.0, the hydronium Ion Concentration is gotten as; [H3O+] = 1 × 10^(-7) M
<h3>How to find the Concentration of an Ion? </h3>
The formula to find the pH of an Ion concentration is;
pH = - log [H3O+]
where;
[H3O+] is the molar concentration of hydronium ion.
We are told that the pH is 8.0. Thus;
8.0 = - log [H3O+]
10^(-8) = [H3O+]
[H3O+] = 1 × 10^(-8) M
Thus, when pH = 7.0, we have;
7.0 = - log [H3O+]
[H3O+] = 1 × 10^(-7) M
Complete question is;
When the fish-tank water has a pH of 8.0, the hydronium ion concentration is 1.0 × 10-8 mole per liter. What is the hydronium ion concentration when the water has a pH of 7.0?
