Question

1.If a solution absorbed violet light, what color would the solution appear to be?

________________

Calculate the concentration of a solution prepared by adding 15.00 mL of
2.00×10^−3 M 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.

______________ M

Answer 1

Draw a color wheel. Draw three lines as diameter lines equidistant around the wheel, label the intersection of the circle with the lines as Red, Orange, yellow, green blue violet. The color absorbed is opposite to the color of the object.

2.
2.00E-3 M x (15.00/50,00) = ?
