Question

Describe an activity to show the test for solubility of following substances.
salt, sugar, sand, sawdust, glucose

Answer 1

Take five clean test tubes and mark them as A, B, C, D and E. Fill each tube by more than half with water. Add small amounts of salt, sugar, sand, sawdust and glucose, respectively in A, B, C, D and E. Mix the contents and wait for a few minutes. Now, observe all the test tubes. You will notice that salt, sugar and glucose are completely dissolved in water, whereas sand and sawdust are not dissolved in water.
This activity concludes that salt, sugar and glucose are soluble in water, whereas sand and sawdust are insoluble in water.
