Drag each label to the correct image. each label can be used more than once. label the samples based on their ph values.

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.

Lemon juice with pH of 2.2, acidic

Tomato juices with pH of 4, acidic

Gastric juices with pH of 1 , acidic

Bleach with pH of 13, alkaline

Baking soda with pH of 9, alkaline

Salt solution with pH of 7, neutral

oh it is true if thats what you are asking

put the answers   and i could answer.
