प्रश्न
Distinguish by a chemical test sodium hydroxide solution and ammonium hydroxide solution.
Advertisements
उत्तर १
These salts can be distinguished by using metal cations like calcium. When we add calcium salt to sodium hydroxide and ammonium hydroxide, then a white curdy ppt. is formed only in the case of sodium hydroxide.
उत्तर २
With sodium hydroxide solution Ca(NO3)2 sol. gives a fine, milky white precipitate of Ca(OH)2 which is insoluble in excess of NaOH.
\[\ce{Ca[NO3] + 2NaOH -> \underset{milky white ppt}{2NaNO3} + Ca[OH]2\downarrow}\]
Whereas ammonium hydroxide solution with calcium nitrate solution Ca[NO3]2 has no reaction.

Distinguish by a chemical test sodium carbonate and sodium sulphite.
Salts A, B, C, D and E undergo reactions (i) to (v) respectively. Identify the anion present in these salts on the basis of these reactions.
- When silver nitrate solution is added to a solution of A, a white precipitate, insoluble in dilute nitric acid, is formed.
- The addition of dilute hydrochloric acid to B produces a gas which turns lead acetate black on paper.
- When a freshly prepared solution of ferrous sulphate is added to a solution of C and concentrated sulphuric acid is gently poured from the side of the test tube, a brown ring is formed.
- When dilute sulphuric acid is added to D, a gas is produced which turns acidified potassium dichromate solution from orange to green.
- The addition of dilute hydrochloric acid to E produces effervescence. The gas produced turns lime water milky but does not affect acidified potassium dichromate solution.
