C4.2.1 - Reactions of acids with metals

Cards (3)

  • Metal + Acid
    Salt + Hydrogen
  • Why are metal + Acid reactions redox reactions?
    redox reaction example is when metals react with acids. When a metal reacts with an acid, the loss and gain of electrons occurs simultaneously. This is known as a redox reaction, where spectator ions are present.
  • How to name salts?
    salt is any compound formed by the neutralisation of an acid by a base.
    The name of a salt has two parts. The first part comes from the metal, metal oxide or metal carbonate. The second part comes from the acid.
    You can always work out the name of the salt by looking at the reactants:
    • nitric acid always produces salts that end in nitrate and contain the nitrate ion, NO3–
    • hydrochloric acid always produces salts that end in chloride and contain the chloride ion, Cl–
    • sulfuric acid always produces salts that end in sulfate and contain the sulfate ion, SO42–
