Question

.Which of the following metals can displace all other three metal from their salt solution?(a.)iron. (b.)silver. (c.)copper. (d.)zinc *
c

Answer 1

Answer:

Explanation:

Zinc is present above iron and copper in the activity series so it can displace both iron and copper from the salt solution. but question mention about other 3 so answer is none of these.

The metals copper, silver gold and platinum are less reactive than hydrogen and they do not replace hydrogen from water or acid. Examples for metal-displacement reactions: Zinc can displace copper from copper sulphate solution and iron from ferrous sulphate solution. So zinc is more reactive than iron and copper.
