Question

which acid - base chemical reaction is irreversible? (1 point)
weak base added to water
weak acid added to water
strong acid added to water
water on its own

Explanation:

When a strong acid is added to water, it completely dissociates into its ions. This dissociation is essentially irreversible because the strong - acid has a high tendency to donate a proton and the resulting conjugate base is very stable. Weak acids and bases in water exist in an equilibrium state with their conjugate forms, and water on its own undergoes a very slight auto - ionization which is also an equilibrium process.

Answer:

strong acid added to water
