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

<span>pOH = -log(8.6 x 10 ^-5)
</span><span>pOH = 4.07
</span><span>
To calculate the pH we use the relation of pOH and pH, expressed as:
</span><span>
14 = pOH + pH
</span><span>pH = 14 - 4.07 = 9.93
</span><span>pH = -log [H+]
</span><span>[H+] = 10^-9.93 = 1.16 x 10^-3 M</span>
