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 check off 0.05g of Chromium(III) Nitrate to the beaker. Then, add 17 mL of distilled water and neat until the solid is dissolved. 3.Obtain a final 50-mL beaker and add 0.05 grams of the dark heart to the beaker. Add 17 mL of distilled water and mix with a stir bar until the solid is completely dissolved. enter the enigmatical number of the solid in the lab report. 4.Go to your Mea certain(predicate)Net station and dig it on by wringing ON/OFF. 5.Once the station has been activated, condense the important 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 physical exercise 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 clear on in. Leave the minimum at 0. Press count on 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 electronic computer address the min and max wavelengths will be mingled with 250nm to 850nm. To remove these values, press DISPLAY. 8.Next add 3.00 mL of the Iron(III) Nitrate shank made in step one to a cuvette. Do the same for the Chromium(I! II) Nitrate solution and the unknown solution. Make accepted the cuvettes are at least ¾ full to ensure entropy collected is accurate. Next, add 3.00 mL of water to a fourth cuvette. Also, pay back sure the outside of the cuvettes are dry. 9.Go to the spectrophotometer and start out sure the toggle switch is set to ON. Press consume off NUMBER and enter the number of your station and because press ENTER. There will be a fixate to glance over message after ENTER is pressed. 10.Insert the black...If you emergency to get a full essay, order it on our website: BestEssayCheap.com
