Your teacher will let you know which questions you should focus on: 1. Describe the general reaction between silver nitrate and potassium halides, and how the halides can be told apart. [2 marks] 2. Describe the general reaction between sodium hydroxide and metal ions, and how the metal ions can be told apart. [3 marks] 3. Describe the general reaction between barium chloride and sodium carbonate/sulfate, and how the carbonate/sulfate can be told apart. [2 marks]
