Investigating solubuility

10.05.17

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



Method:
Fill beaker up with water to 100 mL .
Add a level teaspoon of baking soda. A level teaspoon is obtained by running your ruler cross the. edges of the teaspoon.
Stir till the baking soda has dissolved .
Repeat 2 and 3 until baking soda has stopped dissolving.
Record how many tablespoons were added.
Repeat this method with table salt.

Amount of tablespoons added:
Baking soda: 1
Table salt: 3


Result 
Solute.         Number of teaspoons that dissolved in 100 mL of water.
Baking soda: 0
Table Salt:2

Conclusion: We have discovered that table salt is more soluble than baking soda because salt dissolved and baking soda didn't.
