Investigating Solubility

10/05/17

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.

Method

1} fill the beaker with 100 ml 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 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 teaspoon of baking soda were added.

6}repeat the experiment, with the table salt.

Result

is that the baking soda did not dissolve in the 100 ml water but the salt dissolved both times when I added 2 teaspoons.

Conclusion

That the sometimes baking soda does dissolve in water but salt dissolves all the time.
