Question

A student dissolved 0.44g of copper wire and followed all steps described in the copper cycle experiment to obtain solid copper. After performing the series of reactions a student weighed a total mass of 24.61g on the scale. This mass included the filter paper mass of 0.23g and the watch glass of 24.19g. Calculate the % recovery for this experiment. %recovery= final mass of copper grams divided by initial mass of copper grams

Answer #1

Initial mass of Copper = 0.44 g

Mass of filter paper = 0.23 g

Mass of watch glass = 24.19 g

Mass of filter paper and watch glass = 0.23 + 24.19 = 24.42 g

Total mass = 24.61 g

Mass of copper recovered = 24.61 – 24.42 = 0.19 g

% recovery = Mass of copper recovered /Initial mass of Copper *100

% recovery = 0.19 g / 0.44 g*100 = 43.18182 % = 43.18 %

    Lab procedure: This laboratory exercise involves the use of dilute sulfuric acid (H2SO4) to leach copper from a synthetic copper-containing ore, malachite. This technique is known in the mining industry as solution mining. The soluble copper is then filtered to remove unreacted ore (the residue) from the filtrate containing the copper+2 ion. The copper in the filtrate is then treated with metallic magnesium to precipitate the copper as the familiar orange-brown metal. This copper is dried and weighed. From these...
