Which of the following occurs when hydrogen chloride gas is dissolved in water to form hydrochloric acid? A) A complex between HCl and water is formed. B) H⁺ is transferred from HCl to water. C) H⁺ is transferred from water to HCl. D) There is no reaction, HCl molecules remain present.

Question

Quizplus · Accepted Answer

When hydrogen chloride gas dissolves in water, a transfer of a proton (H+) from the hydrogen chloride molecule to the water molecule occurs, resulting in the formation of hydronium ion (H3O+) and chloride ion (Cl-). Therefore, the transfer of H⁺ from HCl to water occurs, making option B the correct choice. Option A is incorrect because the formation of a complex is not observed. Option C is also incorrect because the transfer of H⁺ occurs from HCl to water, not the other way around. Option D is incorrect because a reaction does occur, resulting in the formation of hydrochloric acid.
