1. (a) Write balanced molecular equations for the following potential precipitation reactions. Indicate the states of reactants and products [(aq) or (s)]. (b) In those cases where a precipitate forms, write the net ionic equation. If there is no reaction, state "No reaction." 2. Each of the following salts can be prepared from an acid and a base. Write the balanced molecular equation and the net ionic equation for the preparation of each. Indicate states of the reactants and products [(aq),(s),(1)]. Review solubility rules if necessary to determine the solubility of the reactants. (a) KCH3CO2 (aq) (b) CsNO3(aq) (c) Na2CO3 (aq) 3. Assume that 6.2220g of K4P2O7 is dissolved in enough water to make 100.0mL of solution. (a) What is the molarity of K4P2O7 ? (b) What is the molarity of the potassium cation? (c) What is the molarity of the P2O74 anion? The molar mass of K4P2O7 is 330.337g/mol. 4. You have a solution of 0.02088M copper(II) chloride. (a) How many moles of solute are contained in 34.88mL of solution? (b) How many grams of solute are contained in 34.88mL of solution? (c) What volume (in millilitres) of solution is needed to obtain 0.00120 moles of solute? 5. Suppose you need 2.50L of 1.85M hydrochloric acid, but only the concentrated acid (11.6M) is available.
