Experiment 1: Observations of Chemical Changes Abstract: In the lab 1 experiment‚ the objective was to observed properties of various chemical reactions between twelve different basic compounds. Each reaction revealed chemical properties consisting of color change‚ CO2 gas formation‚ and/or precipitate formation. Certain reactions made it possible to distinguish between an acid and a base. Through the results of this experiment‚ chemical properties observed in the reactions could be used to associate

Physical and Chemical Properties Purpose: The Physical and Chemical Properties lab provides the opportunity to investigate the physical and chemical properties of pure chemical substances and analyze the experiment results. Procedure: In the beginning of the experiment‚ I filled two 24-well plates half way with the given chemicals and sucked up these chemicals into their labeled pipets for later use. Following this‚ I performed a number of steps on each of the four test tubes and recorded observations
