The dissolved copper(II) chloride is dissociated into copper(II) and chloride ions. Each copper(II) ion has two less electrons than protons. A scientist wishes to use an electroplating process to reduce the 1.12 g of copper ions to solid copper atoms. To be reduced from the ion form to the atom form, a copper(II) ion must gain two electrons. Each gram of copper(II) ions contains 9.48 x 1021 ions. Determine the total quantity of charge that must be supplied to turn the copper(II) ions into solid copper atpms.arrow_forward
