Solution A is a sodium hydroxide solution Solution B is a weak acid. Solution C is dilute sulphuric acid. Which solution will liberate sulphur dioxide from sodium sulphite ?

Solution A is a sodium hydroxide solution. Solution B is a weak acid. Solution C is dilute sulphuric acid. Which solution will (i) liberate sulphur dioxide from sodium sulphite? (ii) give a white precipitate with zinc sulphate solution? (iii) contain solute molecules and ions?

Solution A is a strong acid Solution B is a weak alkali Solution C is a strong alkali Which solution will give a gelatinous white precipitate with zinc sulphate solution ? The precipitate disappears when an excess of the solution is added.

[i.e. white ppt. insoluble in dil. HCI] ii) Which two solutions will give a white ppt. when treated with dil. HNO_3 & AgNO_3 soln. iii) Which soln. will give a white ppt. when either dil. HCl or dil. H_2SO_4 , is added to it. iv) Which soln. becomes a deep/inky blue colour when excess of ammonium hydroxide is added to it. v) Which solution gives a white precipitate with excess ammonium hydroxide solution.

A white solid P, on strong heating, decomposes to give reddish brown gas R and a residue Q. The residue R is yellow when hot and white when cold. The solution of white solid P in water gives white precipitate S, with concentrated sodium hydroxide. The white precipitate S dissolves in excess of sodium hydroxide solution to form colourless solution. Another sample of the solid P in water is mixed with ferrous sulphate solution and then to this solution are added a few drops of conc. sulphuric acid. A brown ring is formed at the junction of liquids. Answer the following questions: Name the salt formed when S dissolves in excess of sodium hydroxide.
