POh is calculated by the negative logarithm of hydroxide ions concentration. From the given value, we have:

pOH = - log (8.6 x 10 ^-5)

pOH = 4.07

To calculate the pH we use the relation of pOH and pH, expressed as:

14 = pOH + pH

pH = 14 - 4.07 = 9.93

pH = - log [H+]

[H+] = 10^-9.93 = 1.16 x 10^-3 M
