What property of calcium hyroxude makes it useful to farmers?
It is alkali. Farmers can use it to neutralise acidic soil in field so their crops grow better.

Powdered limestone can also be used. Why might powdered limestone be more favorable compared to calcium hydroxide?
It works much faster.
6 of 11
What test can be used to check for carbon dioxide?
Add carbon dioxide to a solution of calcium hydroxide and the solution (Limewater) will turn cloudy.
7 of 11
What causes this cloudiness?
The Calcium carbonate produced.
