Making Salt

             The purpose of the lab was to determine how many grams of sodium chloride (salt) are produced when sodium carbonate is reacted with hydrochloric acid.
             This lab introduced many new tools to us. A lot of them we never used before and we had to be taught to use them in the proper manner. The tools used in this lab are:
             Ø Sodium Carbonate (about ½ teaspoon)
             Ø Water, Paper Towels, Paper and pencil to record results
             There were 3 new items introduced during the process of this lab:
             Theoretical Yield is a calculated value for the amount of the substance that should be made after the reaction. We calculate this by using a conversation with mole ratios and molecular mass.
             Actual Yield is the amount of substance that is made after a reaction. You measure this amount after the entire reaction/experiment is complete.
             Percent Yield is the actual yield divided by the theoretical yield. Then, as in finding any percent, it is multiplied by 100. [(AY TY) * 100]. This is to determine how accurately the lab was performed.
             Begin by attaching the Bunsen burner to the gas outlet. Turn the gas on by twisting the lever until it is parallel with the outlet. Light the burner by flicking the Bunsen burner lighter right above the burner, repeat flicking until the flame is lit. With the piece on the bottom of the burner, you can turn it to adjust the flame. Adjust the flame to the correct height, which is just touching the bottom of the burner's beaker holder on the top. Now take the evaporating dish and wash it with soap and water in the sink. Dry it off with some paper towels. Place the wire gauze screen on the top of the lit Bunsen burner. Place the washed evaporating dish on the top of the wire ga
