1.Calcuate the pH of a solution with [H3O+] = 6.54 x 10-3 M
2.Calcuate the pOH of a solution with [H3O+] = 8.5 x 10-9 M
Note : [H3O+] represents the concentration of H+
Question 1
[H3O+] = 6.54×10-3 M
or
[H+] = 6.54×10-3 M
Using the formula
PH = -log[H+] = -log(6.5×10-3] = 2.187
PH = 2.187
Question 2
First of all we calculate PH
[H3O+] = [H+] = 8.5×10-9
PH = -log [H+] = -log(8.5×10-9) = 8.070
PH = 8.070
now using the formula
PH + POH = 14
8.070 + POH = 14
POH = 5.93
