EXPERIMENT 6 - DETERMINATION OF COPPER IN AN AQUEOUS SAMPLE USING ATOMIC ABSORPTION SPECTROSCOPY Name Date 1. A 0.1430 g sample of copper was dissolved in 20 mL of 6 mol/L HNO3 and diluted to 100.0 mL in a volumetric flask. What is the concentration of copper in g L-1 in the flask? 2. The solution prepared in Q.1 was diluted one hundred times. Now what is the concentration of copper in units of g L-1? 3. The standards were then prepared as described in the procedure and a 5 mL aliquot of unknown was pipetted into each of them. The intercept on the x axis was -4.12 mL How many grams of copper were introduced in the 5 mL addition to each standard? 4. What is the original concentration of Cu in the unknown in g L-1? 5. What is the original concentration of the unknown in ppm**. * This means that there is exactly as much copper in 4.12 mL of standard as there is in 5 mL of unknown. ** In dilute aqueous solution 1 ppm = 1 mg L-1
