In order to find the concentration of each pH value, we need to use the inverse formula of pH, but now to find the concentration of H3O+, the formula is:

[H3O+] = 10^-pH

For pH 1 we have:

[H3O+] = 10^-6.0

[H3O+] = 1*10^-6

ACIDIC

pH 2:

[H3O+] = 10^-5.5

[H3O+] = 3.16*10^-6

ACIDIC

pH 3:

[H3O+] = 10^-3.2

[H3O+] = 6.31*10^-4

ACIDIC

pH 4:

[H3O+] = 10^-7.2

[H3O+] = 6.31*10^-8
