Useful formulas include [H304)= 107, OH-1- 10+00H PH+pOH = 14 and (H20-OH-] = 10-14
The pOH of the solution is 12.0.
The concentration of OH-ions is 1.0 x 10-2 M.
The concentration of H3O+ ions is 100.0 M.
The pOH of the solution is 16.0.

Respuesta :

Answer: The pOH of the solution is 12.0.

Explanation: pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration and pOH is calculated by taking negative logarithm of hydroxide ion concentration.

Answer : The correct option is, The pOH of the solution is 12.0

Explanation : Given,

pH = 2

First we have to calculate the [tex]H^+[/tex] concentration.

[tex]pH=-\log [H^+][/tex]

[tex]2=-\log [H^+][/tex]

[tex][H^+]=0.01M[/tex]

The [tex]H^+[/tex] concentration is, [tex]0.01M[/tex]

Now we have to calculate the pOH.

[tex]pH+pOH=14\\\\pOH=14-pH\\\\pOH=14-2=12[/tex]

The value of pOH = 12

Now we have to calculate the [tex]OH^-[/tex] concentration.

[tex]pOH=-\log [OH^-][/tex]

[tex]12=-\log [OH^-][/tex]

[tex][OH^-]=1.0\times 10^{-12}M[/tex]

The [tex]OH^-[/tex] concentration is, [tex]1.0\times 10^{-12}M[/tex]

Hence, the correct option is, The pOH of the solution is 12.0
