When metal A is placed in a solution of a salt of metal B, thesurface of metal A changes color. When metal B is placed in acidsolution, gas bubbles form on the surface of the metal. Whenmetal A is placed in a solution of a salt of metal C, no change isobserved in the solution or on the metal A surface. Will metal Ccause formation of H2 when placed in acid solution? Rank met-als A, B, and C in order of decreasingreducing strength.
Science behind corrosion-test
Corrosion is defined as an activity that transforms refined metals into more chemically stable forms such as oxide, hydroxide, carbonate, or sulfide. It refers to the slow decomposition of things (typically metals); thanks to chemical and/or electrochemical reactions with their surroundings. Corrosion engineering is the science of preventing and controlling corrosion.
