Aim:  Our aim is to find out and investigate the boiling temperatures of water and water with impurities.  

Hypothesis: My prediction is that the impurities will boil at a higher temperature than the water, or the normal water boiling temperature of a 100 degrees Celsius. I think the reason why is simply because, the impurities are solids so it will boil at a higher temperature than water, since it is already a liquid!

Apparatus:

        Sugar

        Salt

        Cornstarch

        Baking soda

        Food coloring (3 colors)

        4 small beakers

        4 normal-size beakers

        Spatula

        Thermometers

        Measuring cylinder

        Bunsen burner

        Gauze mat

        Tripod

        Water (amount in the method!)

        Safety goggles

        Ice tray

Variables:

        Amount of the Impurities

        Amount of water used

        Temperature of which the impurities was in

Join now!

        Color of the flame used

        The sate of which the impurities was in after refrigerated, whether frozen or not.

Method:

        First of all, gather together these four impurities: Sugar, Salt, Cornstarch and Baking soda.

        Pour 10 mL of water into a measuring cylinder, and then add 10 mL of sugar and mix with a spatula until it dissolves, and pour this mixture into a beaker.

        Follow the same procedure for the rest of the 3 impurities.  Remember to wash out the measuring cylinder after every mixture of the 4 impurities other wise... This won’t be a very fair test! ...
