Question

If the H⁺ ion concentration in a solution is 0.01 M, the pOH of the solution is :

(a) 12 

(b) 10^-10

(c) 2 

(d) 14

Answer 1

Correct Option is : (a) 12

As we know,

pH + pOH = 14

\(\therefore\) pOH = 14 - pH

pOH = 14 + log \([H^+]\)

pOH = 14 + log \(10^{-2}\)

pOH = 14-2

pOH = 12

Answer 2

Option : (a) 12
