Question

Put about 2 g soil in a test tube and add 5 mL water to it.
Shake the contents of the test tube.
Filter the contents and collect the filtrate in a test tube.
Check the pH of this filtrate with the help of universal
indicator paper.
What can you conclude about the ideal soil pH for the growth of
plants in your region?​

Answer 1

The Ideal pH for the growth of plants is 5.5 to 7.0.

Explanation:

• When the pH of the filtrate is checked with the help of universal indicator paper, the value obtained was 6.
• Based upon the pH value the nature of the substance is determined either as acidic or basic or neutral.
• The substance with pH 1-6 are considered as acidic, 7 is neutral, above 7 it is basic.
• As the pH of the obtained filtrate is 6, it means that the soil is slightly acidic. If we apply lime to the soil it will become neutral and can be used for plat growth.
