Question

What is the pOH of a 4.8x10^-10M H+ solution

Answer 1

pH is 9.32 based on the [H+]. we know that:    14=pH+pOH so   pOH would be:   pOH=4.68

Answer 2

Answer : The value of pOH of the solution is, 4.68

Explanation : Given,

Concentration of $H^+$ ion = $4.8\times 10^{-10}M$

As we know that the pH is the negative logarithm of hydrogen ion concentration.

Mathematical representation is :

$pH=-\log [H^+]$

First we have to calculate the pH of the solution.

$pH=-\log [H^+]$

$pH=-\log (4.8\times 10^{-10})$

$pH=9.32$

Now we have to calculate the pOH.

$pH+pOH=14\\\\pOH=14-pH\\\\pOH=14-9.32=4.68$

Therefore, the value of pOH of the solution is, 4.68
