What are the chemical tests for the presence of water using cobalt chloride

Test for water using cobalt chloride paper which turns pink in the presence of water

What are chemical tests for the presence of water using copper sulfate

Test for water using anhydrous copper(II) sulfate which turns blue in the presence of water

How to test for purity of water using melting point

waters melting point is 0 degrees Celsius if a sample of water melts at a temperature below 0 degrees Celsius it is impure

How to test for purity of water using boiling point

waters boiling point is 100 degrees Celcius so if a sample of water boils at a temperature above 100 degrees celcius it is impure

What is the process used to produce distilled water

Distillation

What is removed from the distillation of water

Impurities

Why is distilled water used over tap water in practical chemistry

Distilled water is preferred over tap water in practical chemistry as it lacks impurities. If impurities are in the experiment it can interfere with experiments as well as affect results
