spectrophotometry

Question 1

Matter interacts with light by absorbing and transmitting different wavelengths.

Answer 1

-

Question 2

Spectrophotometry quantitatively describes either the transmittance or absorbance of light by a substance.

Answer 2

-

Question 3

The optimal light wavelength to use for analysis is denoted λmax and is the wavelength at which maximal light absorbance occurs.

Answer 3

-

Question 4

Beer-Lambert Law states that a substance’s absorbance value is directly proportional to its concentration.

Answer 4

-

Question 5

If absorbance can be measured, it can be used to determine the concentration of an unknown solution.

Answer 5

-

Question 6

If a solution is not coloured it is often possible to engineer a situation in which is undergoes a reaction or is conjugated to a coloured compound.

Answer 6
