Disovling science experiment-chemistry and choas

Aim:
My aim is to see if baking soda is more soluble than table salt.

Hypothesis:
I think the baking soda will dissolve more than the salt.

Method:
1: Fill the beaker
2: Use a level teaspoon and add baking soda
3: Stir the water in the beaker until the baking soda has dissolved
4: Do step 2 and 3 again multiple times until no more aking soda will dissolve
5: Record how many teaspoons of baking soda you added until no more would dissolve
6: Do the experiment again with the salt.

Results:

Solute

Number of teaspoons that dissolved into the solution

Baking soda7
Table salt29

Discussion:
We kept going with the salt it took a long time for any to stayvisible we kept adding more and it didn't seem to stop.The baking soda stopped a lot quicker and was very visible after 7teaspoons. The salt made the water cloudy slowly and the baking soda made it cloudy very quickly. The reason the saltdissolved so much is the monecules in the salt and in the water
attract to each other.


Conclusion:
We put in a lot of salt and more salt dissolved than baking soda.
Equipment:
250ml beaker, 100ml mesuaring cylinder, salt, baking soda,
a string rod, a tea spoon and ruler.
