# What is the pH and pOH if the H+ concentration is #1*10^-4#?

##### 1 Answer

#### Answer:

pH=4

pOH=10

#### Explanation:

The following relations have been used to solve the problem

#[H^+][OH^-]=10^-14" " " "(1)#

#pH = -log[H^+]#

#pH+pOH =14 -># this relation is obtained by applying log on both sides of equation#(1)#

Given

#[H^+]=10^-4 => [OH^-]=10^-10#

#pH = -log[H^+] = 4#

#pOH=14-pH=14-4=10#
