Testing Methods for Ammonium and Metal Ions by aarna.bhan is a document available to read on EtoBox.
Ammonium ions can be identified by warming a solution with sodium hydroxide, which releases ammonia gas that turns damp red litmus paper blue. Metal cations are tested with sodium hydroxide to observe color changes or precipitates, with specific reactions for ions like calcium, copper, iron, and zinc. Flame tests can also identify metal cations based on the color of the flame produced, with different ions yielding distinct colors.
