ABSTRACT
The aim of this laboratory exercise is to prepare solutions of known concentration from a solid
(NaCl) and by dilution from a stock solution.Quantitative analysis should be used to determine
the required mass to produce a 100mL solution of 1M NaOH. A slightly different result denotes a
slightly different NaOH concentration, therefore make sure to note the precise quantity.
Calculate the molarity after adding 100mL of distilled water to the NaOH and shaking. Initials,
the date, and your focus should all be recorded on a cassette and saved for later use.
C1V1 = C2V2 is used to make a 5mL stock solution of copper nitrate. In several beakers,
combine the stock solution with various amounts of copper nitrate. Fill cuvettes 3/4 filled with the
unknown sample and reference solutions. Record the results after placing cuvettes in a
spectrophotometer with a 780 nm wavelength. The cuvette contains the unknowable already.
The software for the spectrophotometer will be calibrated and configured for the test. To
conclude, increase in the concentration results in increase of wavelength.
