Question
A solution having hydrogen ion concentration is 0.0005 g eqvt./litre, its pOH is :
Options
A.8.2798
B.10.6990
C.12.7854
D.13.3344
Solution
pH = - log [H+] = - [5 × 10-4]
= 4 - log5 = 4 -[log10 - log 2]
= 3 + log 2 = 3.3010pOH = 14 - pH = 14 - 3.3 = 10.7
= 4 - log5 = 4 -[log10 - log 2]
= 3 + log 2 = 3.3010pOH = 14 - pH = 14 - 3.3 = 10.7
