Determination of ascorbic acid in vitamin C tablets: which analytical approach is better; volumetric or spectrophotometric analysis?
Catra wanted to determine the concentration of copper(II) chloride at an unknown concentration .She began by trying to determine the value of epsilon (ε) using beers law for copper(II) chloride. Catra remembered in lab when they wanted to solve for epsilon they would test the absorbance for three different concentrations of a known solution and then graph it. Catra got frustrated and asked Shera what to do next to determine epsilon. What should Shera tell Catra?
