156) A mixture of salts (Na₂SO₃ + K₂Cr₂O₇) in a test tube is treated with dil. H₂SO₄ and resulting gas is passed through lime water. Which of the following observations is correct about this test?

Solution in test tube becomes green and lime water turns milky

Solution in test tube is colourless and lime water turns milky

Solution in test tube becomes green and lime water remains clear

Solution in test tube is colourless and lime water also remains clear

Answer is:

Solution in test tube becomes green and lime water turns milky

Explanation:

Na₂SO₃ with dil. H₂SO₄ produces SO₂ gas which turns K₂Cr₂O₇ green and lime water milky.
