Volume of each cu2+-en mixture be identical

Reference no: EM13694993

Problem- 1) Suppose you are asked to record your spectrophotometer readings in percent transmittance (%T), instead of absorbance (A), and then to conver the %T readings to the corresponding absorbances. What is the corresponding absorbance for %T=50?

2) Why is it important that the total volume of each Cu2+-EN mixture be identical? The experiment is (Determining the Formulas of Copper(II)-Ethylenediamine Complex Ions by Spectrophotometry)
