What is a voltaic cell in which the electrolyte is in the form of a paste called?

• A. Wet cell
• B. Dry cell
• C. Lead-acid cell
• D. Alkaline cell

Answer: (B)

A voltaic cell in which the electrolyte is in the form of a paste is referred to as a dry cell. This type of cell uses a paste-like electrolyte, which allows it to be sealed in a way that prevents leakage, making it convenient for portable applications such as batteries used in flashlights or remote controls. The dry cell typically contains a zinc anode and a carbon cathode, with the electrolyte paste facilitating the chemical reactions needed to generate electrical energy.

In contrast, other types of cells, like wet cells, use a liquid electrolyte, and lead-acid cells are a specific type of wet cell often employed in automotive batteries. Alkaline cells can be both dry and wet but are typically associated with a specific chemical composition. So, the defining characteristic of a dry cell lies in its use of a paste electrolyte, distinguishing it from other cell types.
