Intro:
Light can act as a wave or a particle, it depends on certain circumstances light can go through. It can interact with different chemicals and telling us what we can see in a solution. Light can show the different types of factors that can occur in the state of the substance such as solid, liquid or gas.
Light can be absorbed by objects, which means light must be absorbed by a chemical substance in order for the photoelectric effect to take place. This effect is known for electron being emitted when light is shined upon it and photons may or lose the absorbance.
Beer-Lambert law:
This is when light effects the concentration on the absorbance which contain electrons interacting with the photons.
E.g. when concentration is low, absorbance is low and when concentration is high, absorbance also be high as well.
Spectrophotometer: Refer to Mr. Papagapiou lab report
Spectrophotometer has two advantages
1. Capable of transmitting monochromatic light through the solution
2. Allows a standard path length for tested samples
Copper (II) Sulfate:
This is a chemical compound, usually described as a blue crystalline or a powder. It is known as salt having multiplies of compound that can attract water molecules into them
Statement:
How does the concentration of Copper Sulfate (COSO4) compare to the absorbance?
Hypothesis:
The less Copper (II) Sulfate
