In Preparing Calibration Standards A Stock Solution Is Typically First Prepared Then Diluted To Different

Question

In preparing calibration standards, a stock solution is typically first prepared, then diluted to different

concentrations to produce a series of standards. For the analysis of potassium, standards at 50, 150, 450, 1500, and 3000 mg/L K are required. Describe a procedure to first prepare 100 mL of stock solution (3000 mg/L K) using solid potassium sulfate salt K2SO4. Then describe how dilutions would be done to produce 10 mL each of the remaining solutions (50, 150, 450, and 1500 mg/L) using the 3000 mg/L stock
