Lead sulphate from lead carbonate
Give two examples of a mixed salt.
Name a basic salt.
Define an acid salt.
Explain salt hydrolysis. Name two salts which are (a) acidic (b) basic (c) neutral, when dissolved in water.
Select the correct answer from the choices a,b,c and d which are given.Write only the letter corresponding to the correct answer.
An example of a complex salt is
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.
