1. This multipart question deals with an experiment to determine the mass % copper in a mineral sample. The sample does not contain native copper, but instead is a blue and green soft mineral with some impurities in it. a. A sample of 1.305 grams of this mineral is dissolved in concentrated HCI. The sample does not completely dissolve. The insoluble material, including quartz, is removed with centrifugation. The solution now contains copper (II) chloride. A. What is the formula for copper (I) chloride? b. The copper in that solution is precipitated as the carbonate with KaCO, to give a blue/green solid suspended in solution. What is the formula for the precipitate that is formed? c. The solid is then collected by filtration and then dried in an oven to produce 0.7502 grams of the copper (II) carbonate precipitated in the last step. What mass of copper is in the copper (II) carbonate collected? d. What is the mass percent copper in the original mineral sample? 1.
