Based on these electronegativities, HCI would be expected to have polar covalent bonds and contain H+ ions.
- Hydrochloric acid, also referred to as muriatic acid, is HCl. It is a component of the hydrogen halides (HX) family. Due to their propensity to lose a proton in a solution.
- Hydrogen halides are diatomic inorganic molecules that function as Arrhenius acids. Since the X belongs to the halogen family (group 17), it can be fluorine, chlorine, bromine, or iodine.
- In hydrogen chloride, only 17 percent of the hydrogen atom's electron density has been transferred to the chlorine atom. It confirms that the H-Cl bond in the hydrogen chloride is a polar covalent bond, not an ionic bond.
- In hydrogen chloride, the chlorine atom is 127.4 x 10⁻¹² m away from the hydrogen atom, giving the compound a 1.05 D dipole moment.
- 1 D equals 3.33 x 10⁻³⁰ C. m.
- The chlorine atom i will have an equal but opposite charge. e. Therefore, the value of the partial charge in the hydrogen chloride compound is 0.027 x 10⁻¹⁸ C.
Mathematically,
% of ionic character = 16(Xa - XB ) + 3.5(XA - Xb )
=16(3-2.1)+3.5(3-2.1)²
= 14.4+2.835
= 17.235%
:. The nature of HCI is 17.2% ionic
