Q9. What is ph range?
Ans. 
pH range refers to the scale that measures the acidity or alkalinity of a substance.
• pH range is a scale from 0 to 14.

• A pH value of 7 is considered neutral.

• Values below 7 indicate acidity, with lower values being more acidic.

• Values above 7 indicate alkalinity, with higher values being more alkaline.

• For example, lemon juice has a pH range of 2-3, making it highly acidic.

• Baking soda has a pH range of 8-9, making it slight
