ZINC LIBERATES HYDROGEN GAS WHEN REACTED WITH HYDROCHLORIC ACID, WHILE COPPER DOESN'T??????
Please answer my question fast and in easy words
Zinc oxidises (loses electrons) more easily than hydrogen whereas copper does not do so. So, copper does not displace hydrogen from dilute acids.
Hope it helps you #CHEERS
copper is below hydrogen in the reactivity series, thats why
order of reactivity:
any thing that has reactivity higher than hydrogen can react with acids and displace hydrogen. that is the reason why Zn can but Cu cannot.
