Verified step by step guidance1
Identify the compound given: ZnCl2, which is zinc chloride.
Recall that zinc (Zn) typically forms a cation with a charge of +2, written as $Zn^{2+}$.
Recognize that chloride (Cl) is the anion derived from chlorine, which typically has a charge of -1, written as $Cl^{-}$.
Since the formula is ZnCl2, there are two chloride ions for every one zinc ion to balance the charges.
Therefore, the ions present in an aqueous solution of ZnCl2 are $Zn^{2+}$ and two $Cl^{-}$ ions.
