Question

A solution has a [H+] = 1 x 10-12 M, calculate the pOH, pH, and [OH-]. Classify the solution as an acid, base, or neutral solution.

Answer 1

Answer:

[H+] = 1 x 10^-12 M

pH = - log(1*10^-12)

pH = 12

And pOH = 14 - 12 = 2

So,

pOH- = - log(OH-)

2 = - log(OH)

OH- = 1*10^-2 M

The solution pH is more than 7

So this is acidic solution.
