What best describes what happens when an acid such as HCl is mixed with water?

B)A proton from the chlorine nucleus is ejected and captured by a water molecule to form a negatively charged HCl and a new hydronium ion.
C)A hydroxide ion from the water is transferred to the HCl molecule to form a proton and hydronium ion.
D)HCl is not an acid.
E)none of the above

Question

Quizplus · Accepted Answer

When HCl is mixed with water, the hydrogen ion (proton) chemically bonded to the chlorine is transferred to a water molecule, forming a hydronium ion (H3O+) and a chloride ion (Cl-). This is the process of dissociation or ionization of the acid in water.
