1. The limiting reactant is determined in this experiment. a. What are the reactant (and their molar masses) in the experiment? b. How is the limiting reactant determined in the experiment? 2. Experimental Procedure, Part A.2. What is the procedure and purpose of “digesting the precipitate? 3. Two special steps in the Experimental Procedure are incorporated to reduce the loss of the calcium oxalate precipitate. Identify the steps in the procedure and the reason for each step. 4. A 0.879 gram sample of a CaCl2*2H2O/K2C2O4*H2O solid salt mixture is dissolved in approximately 150 ml of deionized water, previously adjusted to a pH that is basic. The precipitate, after having been filtered and air-dried, ahs a mass of 0.284 g. The limiting reactant is the salt mixture was later determined to be CaCl2*2H2O. a. Write the molecular form of the equation for the reaction. b. Write the net ionic equation for the reaction. c. How many moles and grams of CaCl2*2H2) reacted in the reaction mixture? d. How many moles and grams of the excess reactant, K2C2O4*H2O reacted in the mixture. e. How many grams of the K2C2O4*H2O in the salt mixture remain unreacted (in excess)? f. What is the percent by mass of each salt in the mixture?
