Equipment: 250 ml beaker, 100ml ml measuring cylinder, salt, baking soda, something to stir with, a teaspoon and a ruler
My aim today is to find which substance disolves quicker either salt or baking soda, my hypothesis is that baking soda with disolve quicker than salt because baking soda isn't as thick and hard as salt which leads me to believe that baking soda will disolve a lot quicker then salt.
Instructiuons: Fill the beaker with 100ml of water, add a level of baking soda meaning using the ruler and flatting the baking soda, stir the 'solution' until all of the baking soda dissovles, repeat steps 2 and 3 until the baking soda cannot dissolve further, record how much baking soda you added, then repeat with salt, record your findings.
My results
Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions.
The conclusion is that we put in a lot more salt then baking soda because of what salt is made out of.
