Fill in the blanks. ____ acts as a positive pole and ____ as a negative pole in a dry cell.

Short Answer

Expert verified
Answer: In a dry cell, manganese dioxide (MnO2) acts as the positive pole (cathode), and zinc (Zn) acts as the negative pole (anode).

Step by step solution

01

Identify the Materials Acting as Poles in a Dry Cell

In a dry cell, there are two electrodes made of different materials. One of these materials will act as the positive pole, called the cathode, and the other one will act as the negative pole, called the anode.
02

Determine the Positive Pole

In a dry cell, the positive pole is made up of a material that will accept electrons during the electrochemical reaction. The cathode is usually made of manganese dioxide (MnO2).
03

Determine the Negative Pole

In a dry cell, the negative pole is made up of a material that will donate electrons during the electrochemical reaction. The anode is usually made of zinc (Zn). So, to fill in the blanks: - Manganese dioxide (MnO2) acts as a positive pole. - Zinc (Zn) acts as a negative pole in a dry cell.
