multiple choice question\nwater solutions contain ______.\no both h₂o molecules and h⁺ and oh⁻ ions\no h₂o molecules only\no h⁺ and oh⁻ ions only

Answer

Brief Explanations:

Water undergoes self - ionization. In water solutions, there are not only $H^+$ and $OH^-$ ions from the self - ionization of water but also $H_2O$ molecules. Water is a polar covalent compound and exists mainly as $H_2O$ molecules, with a small amount of $H^+$ and $OH^-$ ions due to the equilibrium $H_2O\rightleftharpoons H^++OH^-$.

Answer:

A. both $H_2O$ molecules and $H^+$ and $OH^-$ ions
