In this item, we are instructed that the copper ion is to be reacted with the ion of the chlorine. The ion for copper is positively charged (cation) because it has to lose some of its electron in order to achieve stability. As the charge suggests, the number of electrons is 2.
The counterion (anion) is the chloride which can be written as Cl⁻¹. Since the charge of Cl is only -1, two of this anion should be allowed to react with Cu²⁺ so that the formed molecule is neutral. The formula is therefore CuCl₂.
<em>ANSWER: CuCl₂</em>
