Question
The copper in an aqueous sample was determined by AAS. First, 19.0 mL of unknown were pipetted into each of five 50.0 mL volumetric flask.
The copper in an aqueous sample was determined by AAS. First, 19.0 mL of unknown were pipetted into each of five 50.0 mL volumetric flask. Various volumes of standard containing 12.2 ppm Cu were added to the flasks and the solution were then diluted to volume. 1. Calculate the concentration of standard Cu in each flask 2. Plot the graph of absorbance vs concentration of standard 3. Determine the linear equation of the data 4. Find the concentration of the sample based on the equation obtain
