Name an acidic salt.
Define the meaning of the term 'acid salt'.
Give the name and formula of the acid salt which gives sodium ions and sulphate ions in solution.
From the formulae listed below, choose one in each case corresponding to the salt having the given description :
AgCI, CuCO3, CuSO4.5H2O, KNO3, NaCI, NaHSO4, Pb(NO3), ZnCO3, ZnSO4.7H2O
(a) An acid salt
(b) An insoluble chloride
(c) On treating with concentrated sulphuric acid, this salt changes from blue to white.
(d) On heating this salt changes from green to black.
(e) This salt gives nitrogen dioxide on heating
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. Tabulate your answers in the format given below:
(i) When silver nitrate solution is added to asolution of A, a white precipitate, insoluble in dilute nitric acid, is formed.
(ii) Addition of dilute hydrochloric acid to B produces a gas which turns lead acetate paper black.
(iii) 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, a brown ring is formed.
(iv) When dilute sulphuric acid is added to D, a gas is produced which turns acidified potassium dichromate solution from orange to green.
(v) Addition of dilute hydrochloric acid to E produces an effervescence. The gas produced turns limewater milky but does not affect acidified potassium dichromate solution.
