Ion tests

• Na+ is tested with a flame and produces a yellow flame
• k+ is tested with a flame and produces a lilac flame
• 1)Cu²+ can be tested with a flame and produces a green/blue flame
• 2)Cu²+ can be tested with sodium hydroxide solution and produces a blue precipitate
• 1)Ca²+ can be tested with a flame and produces a red flame
• 2)Ca²+ can be tested with sodium hydroxide solution and produces white precipitate
• Al³+ is tested with sodium hydroxide solution and produces white precipitate
• Fe²+ is tested with sodium hydroxide solution which produces a green precipitate
• Fe³+ is tested with sodium hydroxide solution which produces a orange/brown precipitate (rust)
• NH+ is tested with sodium hydroxide solution and then heat which produces a gas (ammonia) that turns red litmus paper blue
• Cl- is tested with nitric acid and silver nitrate solution which produces a white precipitate
• Br- is tested with nitric acid and silver nitrate solution which produces a cream precipitate
• I- is tested with nitric acid and silver nitrate solution which produces a yellow precipitate
• CO3²- is tested with acid and produces a gas, this gas turns lime water milky
• SO4²- is tested with hydrochloric acid and barium chloride solution which produces a white precipitate
