• metal + acid = salt + hydrogen
• Metal oxide + acid = salt + water
• Metal hydroxide + acid = salt + water
• Metal carbonate + acid = salt + carbon dioxide + water
• Ammonia + acid = ammonium salt
• Hydrochloric acid + metal = metal chloride + hydrogen
• Sulphuric acid + metal = metal sulphate + hydrogen

• What makes up a acid ?

  hydrogen ions (H+)
• What makes up an alkali ?

  hydroxide ions (OH-)
• do more H+ ions make the substance more acidic or alkali?

  acidic

  more H+= more acidic
• What make a strong acid ?


  An acid that completely ionises in a solution so there are no longer any molecules .
