Web1. Set up the Vernier system in DATAMATE as in Experiment 2 and turn on the colorimeter, allow it to warm up (at least 5 minutes) while the standard solutions are prepared. 2. Set the wavelength on the colorimeter to 470 nm using < > arrows on colorimeter. 3. Label six 50 mL volumetric flasks, A–F, for the standard solutions. 4. WebStep-by-step explanation The Vernier GoDirectTM Colorimeter has 4 wavelengths 430 nm, 470 nm, 565 nm, and 635 nm. It is best to use the 470nm setting since it is closest to the theoretical maximum absorbance of Fe (SCN) 2+ around 460 nm.
