Question

Which of these accurately describes why an acid is strong? An acid is strong when it undergoes a reverse reaction. An acid becomes strong when it is mixed with a base. An acid’s strength is due to the amount present in a solution. An acid is strong when it dissociates completely in water.

Answer 1

D. An acid is strong when it dissociates completely in water.

Step-by-step explanation:

Answer 2

An acid is strong when it completely dissociates in water.

Take, for example, hydrochloric acid (HCl), which is a strong acid.

When HCl is put into water, the compound will dissociate completely, yielding hydrated H+ and Cl- ions. This dissociation is pretty close to 100%.
