LONG ANSWER TYPE QUESTION

Question 1. A 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 the milkiness disappeared when the gas was passed in

excess. Identify the substance ‘X’ and write the chemical equations of the reactions involved.​

Answer 2

Answer:

Calcium carbonate on reacting with dilute sulphuric acid release the colourless and odourless gas accompanied by bricks effervescence, which is called carbondioxide. The chemical equation for this reaction is:

CaCO3 + H2SO4 → CaSO4 + H2O + CO2
