Question

What is the pOH of an aqueous solution with a [ OH- ] = 3.76 x 10-9 ?

Answer 1

8.4

Step-by-step explanation:

pOH refers to a measure of hydroxide ion (OH-) concentration. It denotes the alkalinity of a solution. Aqueous solutions at 25 degrees Celsius with

If pOH is less than 7 then an aqueous solution is alkaline, if pOH is greater than 7 then an aqueous solution is acidic and if pOH is equal to 7 then an aqueous solution neutral.

`pOH=-\log \left [ OH^(-) \right ]`

`pOH=-\log \left [ 3.76* 10^(-9) \right ]=8.4`
