Question

The hydrogen ion concentration for a solution with a ph of 3.5 would be

Answer 1

Well I assume you know what is pH. If not then you can ask me. the formula is

pH= -log [H3O+]

if you are given the pH then you do the log inverse on both sides of the equation. So if you are given a pH of 3, then you will do the following:-

3= -log[H3O+]

When you multiply both sided by -1, then you will get,

-3= log[H3O+]

log inverse is to raise -3 to the base 10.

10^-3 = [H3O+]

0.001 = [H3O+]

So in this case pH of hydromium ion is 0.001 M

Hope this helps!
