Question

Metals which are higher up in the activity series can be obtained from their oxides by :

• A. reduction by precipitation
• B. electrolytic reduction
• C. aluminothermic reduction
• D. self-reduction

Answer 1

The correct option is B electrolytic reduction

Metals which are higher up in the activity series are very reactive and can be obtained from their oxides by elecrolytic reduction.

The substance that is the strongest reducing agent (the substance with the highest standard cell potential value in the table) will undergo oxidation. The substance that is the strongest oxidizing agent will be reduced. The overall reaction which takes place is called displacement reaction
