A silvery gray peice of metal is to added a clear and colorless liquid containing acid. The metal bubble and disappears. The liquid turns bright green. Have one or more new substances formed? Explain your answer.
Yes, one or more new substances have formed in this reaction. The bright green color of the liquid indicates a chemical change has occurred. The silvery gray metal likely reacted with the acid in the liquid to form a new compound, which dissolved in the liquid, resulting in the disappearance of the metal. Additionally, the change in color from clear and colorless to bright green also suggests the formation of new substances with different chemical properties.
