Question

A white coloured water insoluble substance X on reacting with dilute H₂SO₄ released a colourless and odourless gas accompanied by brisk effervescence. When the gas was passed through water, the solution obtained turned blue litmus red. On bubbling the gas through lime water, it initially became milky and milkiness disappeared when the gas was passed in excess. Identify the substance X‘. Write its chemical equations of the reactions involved.

Answer 1

Answer:

Your answer is Sodium carbonate

When Sodium Carbonate reacts with Sulphuric acid It gives out Co2 +H2O+NaCl

--->Co2 when Passed in water it gives Carbonic acid

--->When CO2 is passed through Lime water Is forms CaCO3 which makes it milky

Additional Information:-

• When Metal carbonates or Metal hydrogen carbonates react with acid they form Salt+water+CO2

Hope it helps!
