A 0.005 M potassium hydroxide solution is an example of what type of solution? *
poizon [28]

Answer:

Basic solution

Explanation:

A solution containing 0.005 M potassium hydroxide has a pH of;

pOH= -log[0.005]

pOH= 2.3

But pH+pOH=14

Therefore;

pH= 14-pOH

Hence;

pH= 14-2.3= 11.7

A solution having a pH of 11.3 is clearly a basic solution because this pH indicates a substance that is basic in nature. Hence the answer given.
