1) Acidic - gastric juices pH 1, lemon juice pH 2.2, tomato juice pH 4.

2) Neutral - salt solution pH 7.

3) Alkaline - baking soda pH 9, bleach pH 13.

pH is a numeric scale used to specify the acidity or basicity of an aqueous solution.

When pH is less than seven (pH<7), solution is acidic.

When is equal seven (pH = 7), solution is neutral.  

When pH is greater than seven (pH > 7), solution is basic.

Explanation:

The pH of the solution is a numerical figure which tells us about the acidity or alkalinity of the solution.

  • If the pH of the solution is less than 7 then it is considered as acidic.
  • If the pH of the solution is more than 7 then it is considered as alkaline.
  • If the pH of the solution is 7 then it is considered as neutral.
