in organic che selectivity means when we get two product but is in major quantity then we select the product major

specificity means we get only one type of compound and is 100 percent

We use Potassium Dichromate solution for the calibration of UV-Visible Spectrophotometer in UV region. My question is to calibrate visible region which solution could be used in photometric accuracy
