Testable Question To observe and compare single and ouble displacement reactions Hypothesis Single Displacement: If the reaction that occurs is single displacement then an increase in different reactants will result in creating a single compound/reactant. Double Displacement: If the reaction that occurs is double displacement then an increase in reactants will reesult in creating two or more compounds/reactants. Experimental Design Part A: A large well plate was placed on the lab station, each well was filled with either copper (II) nitrate, magnesium nitrate, or zinc nitrate. Added to each of the wells was three strips of copper wire, magnesium ribbon, and zinc metal (powder form). Using a toothpick, you submerged the metals in the liquid and ensured they did not touch. After 1-2 minutes results were recorded in a observation table. The independent variable in this reaction is the amount of copper wire, magnesium ribbon, and zinc metal (powder form) and the 1/3 filled wells of copper (II) nitrate, magnesium nitrate, or zinc nitrate. The dependent variable in this reaction is the reaction that occured between the metals and the solution. Part B: Using the same experimental design as part A, three drops of sodium…show more content…
Sodium cabonate, the second compund, was added to the various different metal solutions, the first compound, these two different compounds switch places. As my hypothesis states this reaction is called a double displacement because two different compounds switch places. We know that this is a double displacement reaction because the metal solutions reacted with the sodium carbonate making it evident another reaction is taking place. We know this reaction occured because many different chemical changes were evident such as metals changed colour and dissolved, as well as the solutions changed colour and turned
