Multiple Choice

Which metallic ion is present in copper(II) chloride?

Cl^{-}

Cu^{+}

Cl^{2+}

Cu^{2+}

Verified step by step guidance

Identify the chemical formula given: copper(II) chloride is written as CuCl\_2.

Understand the Roman numeral in the name 'copper(II)' indicates the oxidation state of the copper ion, which is +2.

Recognize that chloride ions (Cl\^-) have a charge of -1 each.

Since there are two chloride ions, their total negative charge is 2 \times (-1) = -2, which balances the +2 charge of the copper ion.

Conclude that the metallic ion present in copper(II) chloride is Cu\^{2+}.
