When dilute hydrochloric acid is added to a sodium compound A, then brisk effervescence of a gas B is produced. On passing this gas through lime-water, the lime-water turns milky forming an insoluble compound C. When excess of gas is passed, the insoluble compound dissolves forming a soluble compound D.(a) What could be compound A?(b) Name the gas B.(c) Name the insoluble compound C.(d) Name the soluble compound D.
