Question

What range of values on the pH scale represent solutions with a higher ratio of hydroxide (OH-) ions​

Answer 1

The solution with a higher ratio of hydroxide ( OH -) ions shows the PH value between 7.1 to 14.0

The PH scale ranges from 0 to 14.

• The PH of solution is a measure of its acidity or alkalinity .

• High Concentration of hydroxide ions results in high PH.

• The overall concerntration of hydrogen ions is inversely proportional to PH and can be measured on PH scale.

• PH of natural water is neutral, it has PH 7.

•Anything below PH 7 ( 0 to 6.9) is acidic.

• Anything above OH 7 ( between 7.1 to 14) is alkaline.

• PH of blood is 7.4 hence it is alkaline.

• PH of urine is 6, it's acidic

• PH of Gastric acid is 1.

• A change in one unit of PH scale represents a change in concentration of hydrogen ions by a factor of 10.
