To see if salt or baking soda dissolves more
Hypothesis:
I think that the baking soda will dissolve more because powder is thinner and can disappear quickly when it is dissolving in a liquid, in my opinion.
Equipment: A 250 mL beaker, 100 mL measuring cylinder, salt, baking soda, a stirring rod, a teaspoon and a ruler.
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 of the baking soda has dissolved.
4. Repeat steps 2 and 3 until no more baking soda and then it will dissolve into the solution.
5. Record how many teaspoons of baking soda were added.
6. Repeat the experiment, with the table salt.
Results:
Discussion:
This experiment involved dissolving a solute. The first substance we dissolved was table salt, the results we got came upto 5 teaspoons and i'm pretty happy of how many teaspoons we did. Our results means that the mixture of salt and water can dissolve really well together.
For our second experiment, this time we did a mixture of baking soda and water, the results we got came upto 2 teaspoons. Our result means that the mixture of baking soda and water can not combine very well together.
Conclusion:
My hypothesis that I thought would combine together well was baking soda, but I found out at the end of my results was wrong. The table salt dissolved more in the water than the baking soda and had more teaspoons displayed. I thought that the baking soda would dissolve more because its particle size was much more smaller than the table salt.
