What is a positive electrode made of?

The positive electrode is a rod made of carbon that is surrounded by a paste of manganese (IV) oxide, zinc chloride, ammonium chloride, carbon powder, and a small amount of water. The reaction at the anode can be represented as the ordinary oxidation of zinc:

Which electrode is attached to the positive terminal of a battery?

The electrode attached to the positive terminal of a battery is the positive electrode, or anode. cathode The negative electrode during electrolysis. anode The positive electrode during electrolysis. During electrolysis: cation An atom or group of atoms that have lost electrons and become positively charged.

What is a positive electrode in a battery?

The electrode attached to the positive terminal of a battery is the positive electrode, or anode. A substance which, when molten or in solution, will conduct an electric current. The decomposition (breakdown) of a compound using an electric current. They just provide a surface for ions to gain or lose electrons so they form products.

What type of electrolyte is used as a positive electrode?

A paste of Ammonium Chloride or Zinc Chloride (black in color in the above image) is used as electrolyte. The electrolyte has a small amount of moisture. The positive electrode consists of a mass of manganese dioxide with a carbon rod at the center.

What is a negative electrode in a battery?

electrode A conductor used to establish electrical contact with a circuit. The electrode attached to the negative terminal of a battery is called a negative electrode, or cathode. The electrode attached to the positive terminal of a battery is the positive electrode, or anode. cathode The negative electrode during electrolysis.

What type of electrode does a battery need?

Electrolysis needs: dc Direct current. electrode A conductor used to establish electrical contact with a circuit. The electrode attached to the negative terminal of a battery is called a negative electrode, or cathode. The electrode attached to the positive terminal of a battery is the positive electrode, or anode.
