Question
Lead chloride is made up of Pb2+ and chloride ions. Which of the following is the correct formula for the compound they form?APbCl2BPbCl3CPbCl4DPbCl
Solution
The correct formula for the compound formed by Pb2+ and chloride ions is PbCl2. This is because the 2+ charge on the lead ion means it needs two chloride ions (each with a 1- charge) to balance out the charge. Therefore, the correct answer is A: PbCl2.
