Hydrometallurgy To Analyze A Chromite Sample

Part A: Spectroscopy 1.0.05g of Iron(III) Nitrate in a 50-ml beaker. increase 17 mL of distilled water to the beaker and incorporate with a agitate rod until the solid is completely dissolved. 2.Obtain another 50-mL beaker and fix 0.05g of Chromium(III) Nitrate to the beaker. Then, add 17 mL of distilled water and chasse until the solid is dissolved. 3.Obtain a final 50-mL beaker and add 0.05 grams of the dark middle to the beaker. Add 17 mL of distilled water and mix with a stir bar until the solid is completely dissolved. enter the obscure number of the solid in the lab report. 4.Go to your Mea certain(predicate)Net station and wind it on by wringing ON/OFF. 5.Once the station has been activated, printing press the master(prenominal) MENU firing followed by the F5 for a Spectroscopy, and finally F2 for Absorbance. Next, press the SETUP clit to establish parameters for the absorbance. Press F1 to set the limits and drug abuse the arrow keys to tend from th e X to the Y axis vertebra vertebra or from max to min. 6.For this experiment, absorbance go away be recorded on the Y-axis. Set the maximum military capability for 2.0 and press become on in. Leave the minimum at 0. Press move into again. 7.The Wavelength will be recorded on the X axis in nanometers. Leave the settings for the maximum and minimum set at the default values.

Since you will be using a UV-visible computing device address the min and max wavelengths will be betwixt 250nm to 850nm. To remove these values, press DISPLAY. 8.Next add 3.00 mL of the Iron(III) Nitrate resolve made in step one to a cuvette. Do the same for the Chromium(III)! Nitrate solution and the unknown solution. Make authoritative the cuvettes are at least ¾ full to ensure selective information collected is accurate. Next, add 3.00 mL of water to a fourthly cuvette. Also, pay back sure the outside of the cuvettes are dry. 9.Go to the spectrophotometer and sort out sure the toggle switch is set to ON. Press urinate off NUMBER and enter the number of your station and hence press ENTER. There will be a hold to glance over message after ENTER is pressed. 10.Insert the black...If you motivation to get a full essay, order it on our website: BestEssayCheap.com
