Materials Home


Purpose: How will the solubility of different substances be affected by the temperature of the liquid?

Materials:
2 solids                         test tubes                       test tube rack               beaker 
burner and stand       graduated cylinder       2 No. 2 stopper

Procedure:

  1. Add 10 g of 2 solids to 2 test tubes, each containing 10 cm3 of water.
