Title: Physical and Chemical Properties
Purpose: To investigate the chemical properties of pure chemical substances. To investigate the physical properties of pure chemical substances.
Procedure: For this lab we used four test tubes and poured equal amounts of a substance in each test tube. We then observed the color and odor. We then heated the substance and recorded the observation. The next tube we added cold water and observed the effects, then we heated it and observed the effects. Drops from that test tube were then placed on a red and blue litmus paper and observations were recorder. Finally, in the third and fourth test tubes we added HCL and in the other NaOH and observed the effects.
