Aim
To investigate if loss of concentration of chlorine in a swimming pool is dependent upon the wavelength of the colours in the spectrum and if so, which one has the greatest effect?
Hypothesis
It was hypothesized that if the wavelength was increased, the chlorine loss in the swimming pool water would also increase when the amount of water is kept the same.
Background and Theory Review
Swimming pools come in a variety of shapes and volumes but they all consume filtration and chemical treatments to help keep the pool clean. Most swimming pools contain the main parts including a basin, a motorized pump, a water filter, a chemical feeder and multiple drains. All these parts that are connected via PVC plastic plumbing have a function of keeping the pool at a neutral level or what is known as equilibrium (T Harris, 2013).
For a reaction to occur in chemistry, two or molecules must combine and interact with each other making them change. They could be any molecule within any interaction or reaction. Sometimes, there are a cluster of molecules that combine in which a reaction occurs starting at one point and moving to another. When this reaction is completed, new chemicals appear and these chemicals will often go backwards and perform the reaction in a reversed manner turning itself into the
