Highly reactive metals with lower reduction potentials than hydrogen are not obtained by electrolysis of aqueous solutions of their salts since their cations cannot be reduced at cathode in presence of water. Instead of reduction of these metal cations, water undergoes reduction.\n\nAl and Mg are reactive metals with lower reduction potentials.\n\nUsually d-block elements are less reactive and hence can be prepared by electrolysis of their aqueous solutions.\nthe correct and is B)Al and Mg

hi here is your answer Highly reactive metals with lower reduction potentials than hydrogen are not obtained by electrolysis of aqueous solutions of their salts since their cations cannot be reduced at cathode in presence of water. Instead of reduction of these metal cations, water undergoes reduction. Al and Mg are reactive metals with lower reduction potentials. Usually d-block elements are less reactive and hence can be prepared by electrolysis of their aqueous solutions. the correct and is B)Al and Mg hope it helps u dear!!

See this table
Element which is below hydrogen can't be reduced from their aqueous solution
So Al & Mg can't be reduced
Got it Keerthi
-ve reduction potential means they are good reducing agent
positive reduction potential means good oxidizing agent.
please ask your doubts if you don't get
