Question

When hydrochloric acid (HCl) is added to water it dissociates to form H3O+ (aq) and Cl− (aq) as shown below.

HCl (aq) + H2O (l) → H3O+ (aq) + Cl− (aq)

What happened to the electrons in the H-Cl bond? Choose the best answer.
The electrons are transferred to the chlorine.
The electrons separate.
The proton transferred to the hydrogen.
The electrons are attracted to the polar water molecules.
The electrons move closer to the chlorine.

Answer 1

sad

Answer 2

The H^+ (a bare proton with no electrons) attaches to the lone pair of electrons on the H2O molecule to form the H3O^+ ion. The chloride ion has all of the electrons it started with (remember that the electronegativity of Cl is much more than that of H so the HCl molecule is a polar covalent bond and the electrons ae closer to Cl atom than they are to the H atom anyway). I think a is the best choice.

Answer 3

Hidrogen + iodines
