1.	A mixture of salts (Na_(2)SO_(3)+K_(2)Cr_(2)O_(7)) in most tube is treated with dil. H_(2)SO_(4) and resulting gas is passed through lime water . Which of the following observations is correct about this test ?
Answer» Solution in test tube becomes green and LIME water TURNS milky Solution is test tube is colourless and lime water turns milky. Solution in test tube becomes green and limewater remains clear Solution in test tube remains clear and lime water also remains clear. Solution :`Na_(2)SO_(3)` reactswith dilute `H_(2)SO_(4)` to give `SO_(2)` gas which reacts with `K_(2)Cr_(2)O_(7) +` DIL`H_(2)SO_(4)` togive a green solutiondue to THEFORMATION of `Cr_(2)(SO_(4))_(3)`. As wholeof `SO_(2)` gas reacts AWAY ,on passing the resulting gas throughlime water, it remainsclear.
