What term is used to indicate charges solutions contained in wet cell batteries?

The correct answer is an electrolyte.  

An electrolyte is a term, that is, used to indicate charges, which the solutions comprise in a wet cell battery. A wet cell battery refers to the original kind of rechargeable battery. It is usually found in electric utilities, aviation, cell phone towers, and energy storage. The battery comprises a liquid electrolyte like sulfuric acid. On the other hand, a dry cell battery does not comprise a liquid. Smaller dry-cell batteries like lithium ion or alkaline, are generally used in portable electronics, like phones, toys, and laptops.  

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.
