What is the charge associated with each side of the HI molecule? What is the percent ionic character of the H-I bond?

In hydrogen iodide (HI), the hydrogen ion contains the positive charge. The iodide ion has the negative charge. For the percent ionic character of the H-I bond, the dipole and bond distance needs to be given in the problem.

To solve for the percent ionic character,

(Observed dipole moment/Calculated dipole moment) x 100
