Q. How will the action of dilute hydrochloric acid enable you to distinguish between the following:​
(a) Sodium carbonate and sodium sulphite​

Q. (a) Sodium hydroxide solution can be used to distinguish between (i) Iron (II) sulphate solution and (ii) iron (III) sulphate solution; because these solutions give different coloured precipitates with sodium hydroxide solution. Give the colour of the precipitate formed with each of the solution.
(b) What will you observe when barium chloride solution is added to iron (II) sulphate solution?
(c) How will the action of dilute hydrochloric acid on sodium carbonate and sodium sulphite enables you to distinguish between these two compounds?

Q.

Write balanced equations for the reaction of dilute hydrochloric acid with each of the following :
(a) iron,
(b) sodium hydrogen carbonate,
(c) iron(II) sulphide,
(d) sodium sulphite,
(e) sodium thiosulphate solution.
