Question

Study the given soil samples A and B and determine the water holding
capacity and ph of each sample.
​

Answer 1

The answer is as follows:

Explanation:

To investigate the pH of soil samples

• Place the collected roadside and garden dirt in two separate water-filled beakers.
• Slowly pour the soil solution into the test tubes.

• Arrange a funnel spread coated with filter paper in a clean and dry two test-tube.
• Pour the soil solutions into the test tubes one at a time, gently.
• Allow the water to filter thoroughly through the filter paper.
• Fill two test tubes with the collected filtrates (soil) to determine the pH values.
• Add a few drops of universal indicator solution to both test tubes with the use of a dropper.
• Keep an eye out for variations between the levels of 6.0 and 7.0.

Observation

• The colour of the universal pH indicator changes when it is put to the test tube containing the soil solution.
• The pH colour chart can be used to track these colour changes.
• The pH of roadside soil is 7, while the pH of garden soil is 6.
• The majority of crops thrive in a pH range of 7.0 to 8.0.
