Mix and match PRECIPITATION LAB Objective Predict double replacement reactions, observe them, and express them as using chemical equations, total ionic equations, and net equations.

Make a table to list these, write the chemical formulas, and briefly describe each solution Name Formula Description B2: A1: A2 A3 A list down A1 Copper (II) nitrate A2 Nickel (II) nitrate A3 Cobalt (II) nitrate B list across B1 Sodium carbonate B2 Sodium chloride

EXAMPLE A1 Copper (II) nitrate Cu(NO3)2 Blue clear liquid

Predict products and predict if the reaction between A and B happens Name Formula Description B2: A1: Predict products Note solubility Predict A2 A3 Predict based on double replacement Write formula of each product Check on the solubility chart and note If both dissolve, no reaction If there is a precipitate, reaction

Example block at intersection of A1 and B1 CuCO3 I NaNO3 S Predict reaction? + or -

Mix B1: Name Formula Description B2: A1: Predict products Note solubility Mix and observe A2 A3 In spot plate, set up reactions between A and B chemicals, 6 reactions in all Combine 3 drops of each in wells of spot plate and record observations

Example block at intersection of A1 and B1 CuCO3 I NaNO3 S Predict reaction? + or - Describe what you actually see when you mix 3 drops of each chemical in the well between them

Write For TWO reactions: For TWO non-reactions Write chemical equation Write total ionic equation Write net ionic equation For TWO non-reactions Explain why the reaction did not happen using the numbered solubility rules
