A solution has pH less than 7 and reacts with a metal carbonate to release a gas. By which test will this gas be identified?

Answer and explanation

Correct answer: Turning limewater milky

A pH below 7 identifies the solution as acidic. Acids react with metal carbonates according to the pattern acid + carbonate → salt + water + carbon dioxide. Carbon dioxide is confirmed by passing it through limewater; insoluble calcium carbonate forms and makes the limewater milky. A glowing splint is associated with oxygen, while the litmus and white-fume choices do not identify carbon dioxide.
