A water insoluble substance A on reacting with dilute H2SO4 releases a gas which turns a paper dipped in acidified potassium dichromate solution green. When the gas is passed through lime water, the solution obtained turns blue litmus red. On bubbling the gas through lime water, it initially became turbid and the turbid nature disappeared when the gas is passed in excess.
