Question 1 Report

Which of the following metals will liberate hydrogen from steam or dilute acid?
Answer Details
The metal that will liberate hydrogen from steam or dilute acid is iron. When iron reacts with steam or dilute acid, it forms iron oxide or iron (II) salt and hydrogen gas. This is because iron is more reactive than copper, lead, and mercury, and it can displace hydrogen from water or acid. Copper, lead, and mercury are less reactive than iron, so they cannot displace hydrogen from steam or dilute acid.
