Homework Answers
Malachite green is an organic compound which is green in color and malachite a mineral of copper which is green and opaque in appearance.
Because of the similarity in color it is names as malachite green. It is a chloride salt of organic compound.

Post Lab Questions: CI MALACHITE GREEN CRYSTAL VIOLET 1. Why does the malachite green dye elute first? What physical properties does it have that affect it's interaction with alumina and how are those different from crystal violet? 2. Write the reaction of crystal violet with 1 equivalent of HC. 3. Why does adding HCI cause crystal violet to elute more quickly? What changes with it's physical properties and how does that property affect it's interaction with alumina?

In this experiment, you will measure the rate of photosynthesis
in isolated chloroplasts using the dye 2,6-dichloroindophenol
(DPIP). The transfer of electrons during the light-dependent
reaction results in the production of H+. This H+ ion can reduce
DPIP, changing its color from blue to clear. The color can be
quantitatively measured with a spectrophotometer. However, in this
experiment, you will qualitatively analyze your data.
Write a detailed conclusion for your experiment. How did light
affect the time it took for...

1. If a solution absorbed blue-green light, what color would the solution appear to be? Hint: Table I, at the beginning of the experiment, will help you answer this one. 1. Calculate the concentration of a solution prepared by adding 15.00 mL of 2.09 ~ 10-3M KMnO4 from a buret into a 50.00 mL volumetric flask, which is then filled to the 50.00 ml graduation mark with distilled water.

6. An experiment is carried out to try to distinguish between cylinders of copper, stainless steel and brass on the basis of densities. The densities are 8.93 g/cm for copper, 7.75 g/cmº for stainless steel and 8.40 g/cm for brass. The mass of a metal cylinder is measured to be 42.00 g (4 sig figs), and its volume is measured to be 5 cm (1 sig fig). Why is it not valid to identify the cylinder as being made of...
