A gas which turns lead acetate solution black.

A gas which turns lead acetate paper black.

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 a solution 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-tube, 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 lime water milky but does not affect acidified potassium dichromate solution.

Salts A, B, C, D & E undergo reactions i] to v] respectively. Identify the anion present in each salt.i] When AgNO_3 solution is added to a soln. of A, a white precipitate, insoluble in dilute nitric acid, is formed. ii] Addition of dil. HCl to B produces a gas which turns lead acetate paper black. iii] When a freshly prepared solution of FeSO_4 is added to a soln. of C and conc. H_2SO_4 is gently poured from the side of the test-tube, a brown ring is formed. iv] When dil. H_2SO_4 , is added to D a gas is produced which turns acidified K_2Cr_2O_7 soln. from orange to green v] Addition of dil. HCl to E produced an effervescence. The gas produced turns limewater milky but does not effect acidified K_2Cr_2O_7 soln.

Two inorganic compounds A and B were heated in a dry test tube. A evolved a colourless gas which turned lead acetate paper black and B evolved a gas which turned lime water milky. The anions in A and B respectively are :

The sodium extract on acidification with acetric acid and then adding lead acetate solution gives a black precipitate. The organic compound contains.

Componds (A) and B are treated with dilute HCl separately. The gases liberated are Y and Z respectively. Y turns acidified K_2 Cr_2 O_7 paper green while Z turns lead acetate paper black. The compounds A and B are respectively :
