Quick
in an aqueous solution, 42% of a substance dissociates to release hydronium ions. which of the following statements is true for the substance?
it is a weak acid.
it is a weak base.
it is a strong acid.
it is a strong base.

A strong acid will dissociate completely in water to release hydronium ions.

This is a weak acid since it is only 42% dissociated.

Option (a) is the correct answer.

Explanation:

It is known that when an acid is strong then it dissociates completely into the solution of water. Whereas a strong base also dissociates completely into a solution of water.

Also there is little or no reverse reaction of this dissociation.

On the other hand, if an acid or base is not strong enough or weak acid then it will dissociate slightly or partially in a solution of water.

Therefore, when only 42% of a substance dissociates to release hydronium ions then it means it is a weak acid.

explanation:

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
