Question

What is the difference between hydronium ion and hydrogen ion?

• A. When $H^{+}$ is mixed with $H_{2}O$ it forms ${H_{3}O}^{+}$ and hydrogen ion is the nucleus of a hydrogen atom separated from its accompanying electron
• B. When $H^{+}$ is mixed with $H_{2}O$ it forms $H^{+}$ while hydronium ion is nucleus of a hydrogen atom
• C. When $H^{+}$ is mixed with $H_{2}O$ it forms ${H_{3}O}^{+}$ while hydronium ion is nucleus of a hydrogen atom
• D. None of the choices

Answer 1

The correct option is A

When $H^{+}$ is mixed with $H_{2}O$ it forms ${H_{3}O}^{+}$ and hydrogen ion is the nucleus of a hydrogen atom separated from its accompanying electron

Hydronium ion forms when an acid dissolves in water and $H^{+}$ ions interact with water and hydrogen ion is nothing but the nucleus of a hydrogen atom separated from its accompanying electron.

After $H^{+}$ is mixed with $H_{2}O$ it forms ${H_{3}O}^{+}$
