What are the charges of: Zinc ions Silver ions Hydrogen ions Ammonium ions
Zinc = Zn²⁺ Silver = Ag⁺ Hydrogen = H⁺ Ammonium = NH₄⁺
What are the charges of: Nitrate ions Hydroxide ions Carbonate ions Sulfate ions
Nitrate = NO₃⁻ Hydroxide = OH⁻ Carbonate = CO₃²⁻ Sulfate = SO₄²⁻
What are the products in a reaction with: Metal + Oxygen Metal + Water Metal + Acid Acid + Alkali Metal Hydroxide + Acid Metal Oxide + Acid Metal Carbonate + Acid
Metal + Oxygen –> Metal Oxide Metal + Water –> Metal Hydroxide + Hydrogen Metal + Acid –> Salt + Hydrogen Acid + Alkali –> Salt + Water Metal Hydroxide + Acid –> Salt + Water Metal Oxide + Acid –> Salt + Water Metal Carbonate + Acid –> Salt + Water + Carbon Dioxide
What is the chemical name of limewater?
Calcium Hydroxide
What are the solubility rules?
• All group 1 metals and ammonium compounds are soluble • All nitrates are soluble • Almost all sulfates are soluble apart from lead, barium and calcium • Almost all group 7 salts are soluble apart from silver, mercury and lead • Almost all carbonates and hydroxides are insoluble, apart from group 1 and ammonium (rule 1)
