What is the oxidation number of hydrochloric acid?

Answer 1

(Definition of Valence, Valency in Chemistry: a property of atoms or radicals; their combining power given in terms of the number of hydrogen atoms (or the equivalent))

Valence is the number of bonds an atom can form. Hydrogen (H) always has valence 1, so other elements' valences equal the number of hydrogen atoms they combine with. Thus, oxygen (O) has valence 2, as in water (H2O); nitrogen (N) has valence 3, as in ammonia (NH3); and chlorine (Cl) has valence 1, as in hydrochloric acid (HCl).

The valence depends on the number of unpaired electrons in the outermost (and, in transition-elements, the next) shell of the atom's structure. The sharing of the unpaired (valence) electrons in a bond mimics the stable configuration of the noble-gases, whose outer shells are full. Elements that can achieve stable configurations by various combinations have more than one valence.

Answer 2

there is no charge. hydrogen has a +1 charge and chlorine has a -1 charge.

Answer 3

The chemical formula is HCl, and the charge is neutral.

Answer 4

Hydrochloric acid (HCl) has an ionic charge of 0 or a neutral charge.

Hydrogen has a plus 1 and Chlorine has a minus 1, creating a neutral or 0 charge.

Answer 5

As it is, HCl doesn't have a charge because it is not an ion. However, when in water, it fully breaks into 2 ions: H+ and Cl-

Answer 6

The oxidation number ( or state for people outside the US) is +1 for hydrogen and -1 for chlorine

Answer 7

+1 for H

-1 for Cl

Answer 8

+1
