Our objective of this experiment was to become familiar with writing equations for metathesis reactions and including net ionic equations. For part A of the experiment pertaining to metathesis reactions, we combined 16 different pairs of chemicals that were listed on the report sheet to see if these reactions would produce aqueous solutions. We first mixed the solutions in small tubes and recorded the reactions when both chemicals were mixed in the given pair. Some reactions produce precipitate, some reactions produce sediments, and some even gas like substances. Part B of the procedure of the experiment, we place 8.5 g of NaNO3 (Sodium Nitrate) and 7.5 g KCL ( Potassium Chloride) in a 100ml beaker with 25ml of H2O. Then we heated the mixture and stirred it until all the substances were dissolved. Once everything was dissolved, we cooled the solution to 10˚C by dipping the beaker in ice water. While cooling the solution, we stirred the solution with a glass stirring rod until crystals started to form. After the crystals were formed, we filtered the solution into an evaporating dish. With the filter paper, we dried the excess precipitate between two other filter papers until the crystals were completely dry. Then we examined the crystals to find out the crystals shape and the identity of the crystals. Next we heated the evaporating dish that consisted of the filtrate so that a second crop of crystals could form. From here, we repeated the drying process and examined it as well. Finally, we cooled the filtrate to 10˚C and stirred it with a glass rod to obtain the third crop of crystals. In the end, we compared all three sampled of crystals and came to the conclusion that the first and third trials were the same type of crystals while the second was entirely different.
