Which of the following occurs when NaOH is dissolved in water to form a basic solution? A) A complex between NaOH and water is formed. B) NaOH breaks up to form Na⁺(aq), H⁺(aq) and O^2-(aq). C) NaOH breaks up to form Na⁺(aq) and OH^-(aq). D) The water molecule loses an H⁺.

Question

Quizplus · Accepted Answer

When NaOH is dissolved in water, it breaks up into Na+ and OH- ions. Therefore, the correct answer is C, which shows the dissociation of NaOH into Na+ and OH- ions, along with water (H2O) forming into hydroxide (OH-) ions. Choice A is incorrect because a complex between NaOH and water is not formed. Choice B and D are incorrect because they do not represent the correct chemical equation for the dissolving of NaOH in water.
