What is the conjugate acid of H2O?

Understand the Problem

The question is asking for the identity of the conjugate acid formed from water (H2O). In acid-base chemistry, a conjugate acid is the species formed when a base gains a proton (H+). Here, water can act as a base by accepting a proton to form its conjugate acid.

Answer

H3O+

The final answer is H3O+

Answer for screen readers

The final answer is H3O+

More Information

The hydronium ion (H3O+) is formed when a water molecule gains a proton (H+). In this process, H2O acts as a base, and upon accepting a hydrogen ion, it becomes its conjugate acid, H3O+.

Tips

A common mistake is confusing the conjugate acid with the conjugate base. Remember that the conjugate acid is formed by the addition of a proton, while the conjugate base is formed by the removal of a proton.
