|Chemical test||Sodium chloride solution||Sodium nitrate solution|
|Addition of silver nitrate solution||It reacts with silver nitrate to form a white precipitate of silver chloride, which dissolves in excess of ammonium hydroxide.
||It does not react with silver nitrate solution.|
|Chemical test||Sodium sulphate solution||Sodium chloride solution|
|Addition of barium chloride solution||It reacts with barium chloride to form a white precipitate of barium sulphate, which is insoluble in mineral acids.
||It does not react with barium chloride solution.|
|Chemical test||Calcium nitrate solution||Zinc nitrate solution|
|Addition of sodium hydroxide solution||It reacts with sodium hydroxide solution to form a white precipitate of calcium hydroxide, which on further addition of excess sodium hydroxide is sparingly soluble.
||It reacts with sodium hydroxide solution to form white gelatinous precipitate of zinc hydroxide, which on further addition of excess sodium hydroxide reacts to form soluble, complex sodium zincate.
