Question

What is the pOH if the pH is 11.25?

Answer 1

pH+pOH=14
11.25+pOH=14
pOH=14-11.25
pOH=2.75

Answer 2

Answer:

Given pH = 11.25

We know that pH + pOH = 14

Then , pOH = 14- pH

pOH = 14-11.5 = 2.5

Explanation:

What is meant by pH ?

pH stands for power of the concentration of H+ ions in any solution.

The pH table ranges from 0-14.

Substances having pH value as 7 are neutral, that is they are salts.

Substances having pH value ranging from 0 to 7 are acids.

Substances having pH value ranging from 7.1 to 14 are bases.

The reactivity of acids decreases with increase in magnitude.

The reactivity of bases rises with increase in magnitude.
