Determine the cell voltage of an electrochemical cell that consists of two platinum (inert) electrodes with the 0.100MCrCl3/0.0500 M K2Cr2O7in one compartment and 0.100 M FeCl3/0.0700 MFeCl2 in a
Explain how you could calibrate an infrared spectrum. When an infrared spectrum is run, there is a possibility that the chart paper is not properly placed or that the spectrometer is not mechanical
The student then adds 5 mL of an unknown volatile liquid and heats the flask in a boiling water bath at 99.2C(degrees) until all liquid disappears.
When the pump is turned on, the water begins to boil. A flask of water is connected to a powerful vacuum pump. After a few minutes, the same water begins to freeze. Eventually, the ice disappears.
