Bases

Substances that react with and neutralize acids; including metal oxides, metal hydroxides, and metal carbonates.

Alkali

A base that dissolves in water.

Neutralisation

Salts are produced. Example: Acid + alkali.

Naming Salts

Hydrochloric acid produces chloride salts. Sulfuric acid produces sulfate salts. Nitric acid produces nitrate salts.

Study Notes

  • Gas solubility decreases as temperature increases.

Salts Formation

  • Salts are produced through various reactions.
  • Acid + Alkali results in Salt + Water.
  • Acid + Insoluble bases results in Salt + Water.
  • Acid + Metal results in Salt + Hydrogen gas.

Bases

  • Bases neutralize acids.
  • Types of bases include metal oxides, metal hydroxides, and metal carbonates.
  • Many bases are insoluble in water.
  • A base that dissolves in water is called an alkali.

Naming Salts

  • Hydrochloric acid forms Chlorides.
  • Sulfuric acid forms Sulphates.
  • Nitric acid forms Nitrates.
  • Copper Oxide + Hydrochloric acid -> Copper Chloride + water
  • Zinc oxide + hydrochloric acid -> Zinc chloride + water
  • Magnesium oxide + nitric acid -> magnesium nitrate + water

Chemical Reactions Practice

  • Magnesium + Hydrochloric acid -> Magnesium chloride + Hydrogen
  • Lead + Nitric acid -> Lead nitrate + Hydrogen
  • Zinc + Nitric acid -> Zinc nitrate + Hydrogen
  • Copper + Sulfuric acid -> Copper Sulfate + Hydrogen
  • Iron oxide + Nitric acid -> Iron nitrate + water
  • Zinc oxide + Sulfuric acid -> Zinc sulfate + water
  • Lead + Hydrochloric acid -> Lead chloride + Hydrogen
  • Copper oxide + Sulfuric acid -> Copper sulfate + water

Neutralisation

  • Strong acids in solution are a factor of pH level.
