Cadmium hydrogen sulfate is an ionic compound formed by the combination of cadmium (Cd) and hydrogen sulfate (HSO₄⁻) ions. The formula for cadmium hydrogen sulfate is Cd(HSO₄)₂.

Here's how to determine the formula:

* Cadmium (Cd) has a charge of +2.

* Hydrogen sulfate (HSO₄⁻) has a charge of -1.

* To balance the charges, we need two hydrogen sulfate ions for every cadmium ion.

Therefore, the formula is Cd(HSO₄)₂.
