Choose the statement below that is true.
a. a weak acid solution consists of mostly non-ionized acid molecules.
b. the term "strong electrolyte" means that the substance is extremely reactive.
c. a strong acid solution consists of only partially ionized acid molecules.
d. the term "weak electrolyte" means that the substance is inert.
e. a molecular compound that does not ionize in solution is considered a strong electrolyte.

Option (a) is the correct answer.

Explanation:

A weak acid is defined as an acid that dissociates partially when dissolve in water or a polar solvent.

For example, acetic acid is a weak acid and when dissolved in water it dissociates partly into ions as follows.

And, a strong acid is defined as an acid which when dissolved in water dissociates completely into ions.

For example, HCl is a strong acid and when dissolved in water it dissociates completely.

Thus, we can conclude that the statement a weak acid solution consists of mostly non-ionized acid molecules, is true.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
