D. No precipitate will form.
You must recall the pertinent <em>solubility rules</em>:
- Salts of Group 1 elements (K⁺) are soluble.
- Salts containing nitrate ion (NO₃⁻) are soluble.
- Salts containing chloride ion (Cl⁻) are generally soluble.
- Most sulfate (SO₄²⁻) salts are soluble.
The only ion not included in the list is <em>Mg²⁺.
</em>
However, according to the rules, Mg(NO₃)₂, MgCl₂, and MgSO₄ are soluble.
Thus, there is no precipitate.
