Answer:
The same instrument must be used to measure the unknown solution as was used to measure the known (standard) solutions that were used to create the calibration curve.
The analyte in the unknown solution must be the same analyte (or type of analyte) that is present in the known (standard) solutions that were used to create the calibration curve.
Domain and range restrictions must be observed.
Explanation:
Calibration curves are tools necessary in understanding the instrumental response for any analyte.
A calibration curve is obtained by preparing a set of standard solutions with known concentrations of the analyte. The instrument response for each concentration is measured and plotted against the concentration of the standard solution. The linear portion of this plot may be used to determine the unknown concentration of a sample of the analyte.
The equation of the best-fit line is used to determine the concentration of the unknown sample.
Answer:
An Atom
Explanation:
An atom is the smallest unit of matter
Absorption spectrum is a type of spectrum in electron absorbs energy from a source to go from lower energy level to higher energy level.
- Material's absorption spectrum shows the fraction of incident electromagnetic radiation absorbed by the material over a range of frequencies.
- An absorption spectrum is, in a sense, the opposite of an emission spectrum.
