5 5 1 1 Part D-Double Replacement Reactions: In this section, it is important to observe the mixtures you make very carefully. You are looking for the formation of either a precipitate or a gas. If the mixture gets cloudy, that is an indication that a precipitate has formed. 1) Get two medium test tubes. Into one, place about 2 mL of a solution of barium chloride. Into the other add about 2 mL of copper(II) sulfate solution. Note the appearances of the two solutions and then mix them together noting any changes that have taken place. Change(s) that took place when the solutions were mixed: Balanced chemical equation: Balanced ionic equation: Balanced net ionic equation: 57 E /177
