Qualitative Analysis (Cations)

• White precipitate is formed when aqueous sodium hydroxide is added to a solution containing zinc cations
• The reaction between a copper sulfate solution and aqueous ammonia produces light blue precipitate
• The reaction between a Iron(II) sulfate solution and aqueous sodium hydroxide solution produces a green precipitate
• When aqueous sodium hydroxide is added to an aqueous lead(II)nitrate solution in excess, the colour of the precipitate formed is white
• A white precipitate forms when aqueous calcium chloride solution reacts with aqueous sodium hydroxide solution
• A white precipitate forms when an aqueous aluminium chloride solution reacts with an aqueous sodium hydroxide solution
