In alkaline battery, the anode is made up of

Explanation

Anode vs Cathode: In a battery, the anode is the negative electrode where oxidation occurs (loss of electrons). The cathode is the positive electrode where reduction occurs (gain of electrons).Alkaline battery components: An alkaline battery typically has:Anode: Made of a readily oxidizable metal, typically zinc (Zn).Cathode: Made of a material like manganese dioxide (MnO₂) that can accept electrons during reduction.Electrolyte: An aqueous solution of potassium hydroxide (KOH) allows movement of ions between electrodes.Reaction in an alkaline battery:At the anode, zinc metal loses electrons to become zinc ions (Zn²⁺): Zn(s) → Zn²⁺(aq) + 2e⁻These electrons flow through the external circuit to the cathode.At the cathode, manganese dioxide accepts electrons and combines with water to form manganese hydroxide (MnO(OH)): MnO₂(s) + H₂O + 2e⁻ → MnO(OH)(s)Therefore, in an alkaline battery, zinc (Zn) serves as the anode material due to its high tendency to lose electrons and participate in the oxidation reaction.
