  1. Solubility Rules (Page 170) • Most nitrate salts are soluble. • Most salts of sodium, potassium, and ammonium cations are soluble. • Most chloride salts are soluble. Exceptions: Ag+ and Pb2+. • Most sulfate salts are soluble. Exceptions: Ca2+, Ba2+, and Pb2+. • Most hydroxide salts are only slightly soluble. Soluble ones are: Na+, K+, and Ca2+. • Most sulfide, carbonate, and phosphate salts are only slightly soluble.

  2. Clicker #1 When aqueous silver nitrate and aqueous sodium chromate are mixed, what are the formulas of the products? A) Na2NO3 and AgCrO4 B) NaNO3 and Ag2CrO4 C) NaNO3 and AgCrO4 D) Na2NO3 and AgCr2O7 E) NaNO3 and Ag2Cr2O7

  3. When potassium chloride and sodium nitrate are mixed, what precipitate will form? KCl(aq) + NaNO3(aq)→ A) KNO3 B) NaCl C) KCl D) NaNO3 E) No precipitate will form. Solubility Rules Most nitrate salts are soluble. Most salts of sodium, potassium, and ammonium cations are soluble. Most chloride salts are soluble. Exceptions: Ag+ and Pb2+. Most sulfate salts are soluble. Exceptions: Ca2+, Ba2+, and Pb2+. Most hydroxide salts are only slightly soluble. Soluble ones are: Na+, K+, and Ca2+. Most sulfide, carbonate, and phosphate salts are only slightly soluble. Clicker #2

  4. Clicker #3 • Will the resulting solution conduct electricity? A) No. There is no precipitate formed and a solid is required to conduct electricity. B) No. The resulting solution is pure water which does not conduct electricity. C) Yes. The resulting solution is pure water which conducts electricity. D) Yes. The resulting solution contains ions which conduct electricity.

Exceptions: Ag+ and Pb2+. • Most sulfate salts are soluble. Exceptions: Ca2+, Ba2+, and Pb2+. • Most hydroxide salts are only slightly soluble. Soluble ones are: Na+, K+, and Ca2+. • Most sulfide, carbonate, and phosphate salts are only slightly soluble.

  6. Clicker #4 • Is the resulting net ionic equation a chemical reaction? H+(aq) + OH–(aq)→ H2O(l) A) Yes. There is a new compound formed from H+ and OH–. B) Yes. Whenever two compounds are mixed, a chemical reaction always occurs. C) No. A precipitate (solid) must be formed to be considered a chemical reaction. D) No. There was no color change so a chemical reaction did not occur.
