Salts A, B, C, D and E undergo reactions (i) to (v) respectively. Identify the anion present in each salt.
(i) When AgNO3 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 FeSO4 is added to a soln. of C and conc. H2SO4 is gently poured from the side of the test-tube, a brown ring is formed.
(iv) When dil. H2SO4 is added to D a gas is produced which turns acidified K2Cr2O7 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 K2Cr2O7 soln.
How will the addition of barium chloride soln. help to distinguish between dil. HCl and dil. H2SO4.
CO2 and SO2 gas can be distinguished using :
- moist blue litmus paper
- lime water
- acidified K2Cr2O7 paper
- none of the above.
Identity the substance 'R' based on the information given below : The pale green solid 'R' turns reddish brown on heating. It's aqueous solution gives a white precipitate with barium chloride solution. The precipitate is insoluble in mineral acids.
