Experimental Procedure for Part C: Add approximately 2-3 drops of each pair of reactants in the first column to a test tube. Use 0.1 M solutions for all reactants except when noted differently. Record your observations in column Experimental Observations. Be sure to note the formation of a precipitate, any color change, color of precipitate, evolution of a gas, etc. For a "b" reaction, add 6 drops of the indicated reagent to the precipitate that is left in the well plate to determine if it dissolves. Record your observations in your notebook. Table III: Double Displacement Reactions Reactants Experimental Observations la Ba(NO:)2(aq) + K2SO4(aq) Do not write here.
