Question: Which one of the following compounds contains an ion with a 3+ charge?

Option 1: MnBr3. This compound consists of Mn in a +3 oxidation state (Mn3+) coordinated with three bromide ions (Br-). The overall compound is neutral because +3 + 3(-1) = 0. The presence of Mn3+ means there is an ion with a 3+ charge here.

Option 2: K2S. Potassium sulfide contains K+ ions (each +1) and S2- ions (each -2). The possible oxidation states are +1 for K and -2 for S; there is no ion with a +3 charge in this compound.

Option 3: NaF. Sodium fluoride consists of Na+ and F- ions. Sodium typically forms a +1 oxidation state and fluoride a -1 state; neither ion carries a +3 charge in this compound.

Option 4: CuCl2. Copper(II) chloride contains Cu2+ as the cation and two Cl- anions. The copper ion is +2, not +3, so there is no +3 charge here.

Analysis summary: Only MnBr3 involves a metal ion in the +3 oxidation state (Mn3+), while the other compounds feature ions with charges of +1, +2, or -1/ -2, but not +3.
