Summary: Calibration Curve
This lab was meant to help us understand how solutions can reveal information
according to the elements. The amount of concentration is directly proportional to its
absorbency. This information reveals facts that can help determine the density of the
element that was used. The calibration is due to the employment of the constant
wavelength to determine the absorbance of the solution, to a certain amount of a diluted
solute. All these concentrations were measured using spectrophotometer. This machine
can cost up to 3000 dollars. It calculates the absorbance rate of a solution. It emits light
from one side which passes through the solution and a sensor reads the light that
reaches the other side. This then gives off a reading known as absorbance. Absorbance
is directly proportional to the amount of solute present in the solution. This is called
calibration.
What I learned:
As the light wave passes through the solution, light is absorbed according to the amount
of the solute present. This reinforces the law that absorbency is proportional to the
concentration of the solute.
