| What is the H3O+ and OH- concentration of the following solutions? Urine (pH = 6.0) Blood (pH = 7.4) Bile (pH = 8.0) | Urine pOH = 1.00 x 10^-14/1.00 x 10^-6 = 1.00 x 10^-8
Blood pOH = 1.00 x 10^-14/3.98 x 10^-8 = 2.51 x 10^-7
Bile pOH = 1.00 x 10^-14/1.00 x 10^-8 = 1.00 x 10^-6

| Cont..What is the H3O+ and OH- concentration of the following solutions? Urine (pH = 6.0) Blood (pH = 7.4) Bile (pH = 8.0) | Urine [H3O+] = 10^-6.0 = 1.00 x 10^-6 M H3O+
Blood [H3O+] = 10^-7.4 = 3.98 x 10^-8 M H3O+
Bile [H3O+] = 10^-8.0 = 1.00 x 10^-8 M H3O+
