Solution
Baking soda is NaHCO3.
The formula is:
pH = -log10 [H+]
Baking soda has a pH of 9. It is a base, since the pH is above 7.
You first plug 9 into the formula:
9 = -log10 [H+]
Then divide by -1:
-9 = log10 [H+]
Take 10 on each side:
10^-9 = 10log10 [H+]
Simplify:
10^-9 = [H+]
[H+] = 10^-9 mol/L
[H+} = 0.000000001 mol/L
You can use the formula of finding pH in every substance to findout H+ ions in the same.
