Aim: 

To investigate the solubility of baking soda (sodium hydrogen carbonate) and table salt (sodium chloride) to see which is the most soluble in water.

Equipment: 

1) Fill the beaker, 100mL of tap water

2) Add a level teaspoon of baking soda. A level teaspoon is obtained by running your ruler across the edges of the teaspoon

3) Stir the solution until all of the baking soda has dissolved.

4) Repeat steps 2 and 3 until no more baking soda will dissolve into the solution.

5) Record how many teaspoons of baking soda were added 

6) Repeat the experiment, with the table salt.

Solute	Number of teaspoons  that dissolved in 100ml of water
Baking soda	1 Teaspoons
Table salt	5 Teaspoons
