Unknown Mixture Lab Hypothesis
-Unknown Mixtures Lab-
Purpose:
The aim of this experiment was to find out the two substances of the unknown mixture from salt, sugar, dirt, and baking soda by looking at its properties.
Hypothesis: Find the unknown substance by testing it out by heating it, pouring water, vinegar, and observing it .
Procedure: 1) Materials- * 100ml of water * Vinegar * Bunsen Burner * 2 beakers * 1 spatula
2) First, do steps (3-6)to find out the properties of salt, sugar, dirt, and baking powder.
3) Observe and record the appearances of the four known substances.
4) Burn the known substances one by one to see what will happen. When it starts to burn take the beaker off of the burner.
5) Add water to all substances. …show more content…
For this experiment my hypothesis was correct. The purpose of this experiment was achieved by observing and finding out the characteristics of each substance. The sugar turned brown and smelled good when heated, salt turned black and smelled like burnt rubber when heated, dirt turned to mud when water was added, and baking soda started to bubble when vinegar was added. According to table 1 the data shows that the unknown substance had similar characteristics to both sugar and dirt. And so to find out if my hypothesis was correct or not experiments were carried out based on tests that were characteristics of either sugar or dirt. One experiment was heating the unknown substance to check if it would start drying up and bubbling brown. The other was adding water to test if it would turn into mud. Some mistakes that could be improved in the experiment next time is- making sure not to pour a lot of salt into the beaker when heating it, since there was a lot of salt when heating it the smell was more nastier and shocking. Also when heating the dirt not to let it burn for a long time because when washing it, it was hard to get some of the dirt
