Question

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

Explanation:

A strong acid completely dissociates in water. Once it dissociates into ions in water, it does not recombine back into the original acid - molecule under normal conditions, making the reaction irreversible. Water auto - ionizes in a reversible process. Weak acids and bases only partially dissociate in water and exist in an equilibrium state with their undissociated forms, so their reactions are reversible.

Answer:

strong acid added to water
