Automated Chemistry Flashcards
What is the measurement of the amount of light transmitted or absorbed by a colored solution
Spectrophotometery
What is the color that combined with another color and result in white light setting in which the spectrometry is set to measure the intended color wavelength
Complementary color
What is the distance between identical sites on consecutive waves
Wave lengths
What wavelength for invisible light
190 to 390 nm
What wavelength for visible light
390-750 nm
What color has the longest wavelength
Read
What color has the shortest wavelength
Violet
What type of wavelength is the largest it is measured in centimeters
Radio waves
What is the measurement of the light allowed to pass through a solution
Percent transmittance
What is the percent transmittance formula
I x 100/I
What is the measurement of light absorbed by solution
Absorbance
True or false percent transmittance is proportionally related to absorbance
False
_________ is based on the amount of measured molecules binding with a specific reagent
Concentration
The concentration of a solution at a constant light path length and at a constant wavelength and temperature is directly proportional to the amount of light absorbed
Applied: The concentration of a solution is directly proportional to its absorbance
Beer Lambert law
In spectrophotometric instruments what is used to absorb and filter certain wavelengths of light
Complementary monochromator
