My solubility project
by alexander ramsochit
Purpose and Procedure
The purpose of this experiment was to test four different substances in water to see if they were soluble. A substance is soluble if the water is clear and the substance disappears.
Procedure:
Step 1: Pour the baking soda into the cup of water.
Step 2: Take a picture of the baking soda in the water.
Step 3: Stir the cup for 2 minutes.
Step 4: Observe the cup to see if the water was clear and the substance were dissolved.
Step 5: Repeat steps 1-4 for the powdered, table salt and flour.
baking soda before
it was floating in the middle and half of it was on the bottom
baking soda after
after I stir the baking soda it dissolve
powdered sugar before
when I put the powdered sugar in the water it floating on the lower floor
powdered sugar after
after I stir the the powered sugar the water was cloudy
table salt before
when I put the table salt in the water it smelled like warm water and salt and the water was cloudy
table salt after disolved
after I stir still smelled warm water and salt and it dissolved
flour before
when I put the flour in the water it was heavy and some of it went on the bottom
flour after
after I stirred the flour it became mushy and it did not dissolve.
Conclusion
When I added the baking soda, table salt and powdered sugar to the water they all dissolved. I know that they dissolved because the water was clear and I could not see the substances. When I added the flour to the water it did not dissolve. I know that it did not dissolve because the water was cloudy and there was flour still on the bottom of the cup.
