Aim: To see if salt or baking soda dissolves more in water.
Hypothesis: I don't have any theories but I think the baking soda will dissolve faster but it will turn to paste but that is it changing from it's orignal form so it had dissolved.
Equiment: A 250ml breaker, 100ml measuring cylinder, salt, baking soda, a stirring rod, a teaspoon and a ruler.
Method:
1. Fill the breaker with 100ml of tap water.
2. Add a level teaspoon of baking soda. A level teaspoon is obtained by running your ruler across thr edge of the teaspoon.
3. Stir the solution until all of the subtance had dissolved.
4. Repeat step 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 again with salt.
Results:
Discussion: Salt took more spoonfuls to stop dissolving.
Conclusion: The experiment was really good I learn some new stuff about solubility and it ended up being scuccesful, but i didn't really understand it but it was a good experiment.
