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 form 0.05g of Chromium(III) Nitrate to the beaker. Then, add 17 mL of distilled water and slap-up until the solid is dissolved. 3.Obtain a final 50-mL beaker and add 0.05 grams of the dark midpoint to the beaker. Add 17 mL of distilled water and mix with a stir bar until the solid is completely dissolved. enter the inexplicable number of the solid in the lab report. 4.Go to your Mea certain(predicate)Net station and round it on by wringing ON/OFF. 5.Once the station has been activated, argue the primary(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 call the arrow keys to tend from the 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 arrive on in. Leave the minimum at 0. Press figure 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 entropy processor address the min and max wavelengths will be among 250nm to 850nm. To remove these values, press DISPLAY. 8.Next add 3.00 mL of the Iron(III) Nitrate solvent made in step one to a cuvette. Do t he same for the Chromium(III) Nitrate soluti! on and the unknown solution. Make incontestable the cuvettes are at least ¾ full to ensure data 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 confine sure the toggle switch is set to ON. Press gravel off NUMBER and enter the number of your station and whence press ENTER. There will be a induce to glance over message after ENTER is pressed. 10.Insert the black...If you exigency to get a full essay, order it on our website: OrderCustomPaper.com
