Name: Jacobo Carvajal Instructor: Dr. Zhou Title: Lab 6 Calibration Methods and Introduction to UV-Visible Spectroscopy Prelab questions: 1.You will create 1.000L of 100.0 ppm stock solution of Acetylsalicylic acid (ASA, from the pure powder) in a 2 (v/v) % HCl in this lab. 2 (v/v) % HCl means the volume of concentrated HCl and the volume of the diluted HCl is 2:100. Determine the mass of the solute and volume of conc. HCl you are going to weigh out or measure with a graduated cylinder. Show your calculation. b. (5) Describe exactly how you will make. 2.(5) Create dilution tables to create your standards for the external calibration method given a 100.0 ppm solution and a 10.00 mL volumetric flask and a micropipette with a range from 100.0
