Title:
Physical and Chemical Properties
Purpose:
Investigating the chemical properties of pure chemical substances as well as exploring the physical properties of pure chemical substances
Procedure:
1. I half-filled one well of a 24-well plate with 6M HCl and half-filled a second well of the 24-well plate with 6 M NaOH. I then sucked up these chemicals into their labeled pipets. I then set aside for later
2. I performed the following steps on each substance to be tested. I completed all tests of one substance and recorded my observations before proceeding to the next.
a. I placed a 4 small test tube into the wells of my 24-well plate
b. I then placed small amounts of the substances to be tested in each of the 4 micro test tubs
3. First test tube:
a. I examined the color and odor of each substance then recorded it in my Lab Assistant Report.
b. I light the burner fuel wick. Grasped the test tube with the holder and heated the sample by slowly moving it just above the flame. I oberved the effect of heat on each of the substances and noticed if any gasses were released. I recorded
c. I allowed the test tube to cool before storing so the well plate plastic didn’t melt and start a fire because I do not have renters insurance.
4. Second test tube:
a. I added cold water to fill the test tube ¼. I stirred with the glass stirring rod.
b. I lit the burner fuel wick. Grasped the test tube with the holder and heated the sample by slowly moving it just above the flame, making sure the flame was directed toward the top of the water and the test tube’s open end was not pointed at anyone. I then gently heated the water just to boiling point. (observe in hot h20)
c. I tore off approximately ½-cm pieces of both red and blue litmus paper.
d. I allowed the solution to cool, and used the glass stirring rod to then transfer a drop of the solution onto a
