Question

1. For each of the following pairs of aqueous solutions, use the solubility rules to determine whether or not a precipitate will form when they are mixed. Write the names and formulas of any precipitates that form. Refer to the table below (same as Table 4.1 on page 153 of the textbook) for the solubility rules. If yes, write Formula ofl Precipitate Chemical Name of Precipitate Reactants in an aqueous Will a precipitate solution form? a) calcium nitrate + ammonium carbonate b) potassium phosphate + sodium hydroxide 2. Complete and balance the following molecular equation. Then write the total ionic and net ionic equations, including the state of matter (aq, s, I or g) for each substance. Hint: refer to p. 150-151 of your textbook. Molecular equation: NaF(aq) + Pb(NO3)2(09) ► Total lonic Equation: Net ionic equation:
