The metal with does not react with hydrochloric acid is/are:
Open in App
Solution
The correct option is D Copper
Metals react with acids to give metal salt and hydrogen gas. But this is not true for all metals. Only those metals which are more reactive than hydrogen will liberate hydrogen from the acid and forms corresponding metal salt. These metals are placed above hydrogen in the metal activity series.As copper is less reactive than hydrogen, therefore, it will not liberate hydrogen gas when reacted with dilute HCl.
