The pOH of a solution is 9.70. what is the H+ concentration in the solution ?

Scrat [10]

Answer:

The H+ concentration is $10^{-4.3} M$

Explanation:

We know that for any solution,

pOH + pH = 14

Given,

pOH = 9.70,

Therefore using formula,we get,

pH = 14 - pOH,

pH = 14 - 9.70;

pH = 4.30

We also know,

If Concentration of H+ in a solution in C,

Then,

pH = -log(C) ------(Formula 1) and C = $10^{-pH}$ ----(Formula 2)

Therefore,

using formula 2, we get,

C = $10^{-pH}$

C = $10^{-4.30}$ M.

Therefore concentration of H+ in the given solution is $10^{-4.3} M$
