Question 1 Report

Hydrogen can be displaced from a hot alkaline solution by
Answer Details
When a metal is placed into a hot alkaline solution containing hydrogen, the metal can displace the hydrogen from the solution. This is because metals have a higher affinity for electrons than hydrogen does. As a result, the metal will take the electrons from the hydrogen atoms, causing the hydrogen to be released from the solution. In this case, the metal that will displace the hydrogen most effectively is iron (Fe). Copper (Cu), calcium (Ca), and tin (Sn) can also displace hydrogen, but iron is the most effective of the four options.
