Issues Analysis: Should South Australian Water Continued to be Fluoridated? Introduction: Water fluoridation is the exercise of adding fluoride chemicals to a water source in the effort to prevent tooth decay. (Unknown‚ 2016) Experimentation of water fluoridation began in the early 1800’s when an increase of people began to show symptoms of mottled tooth enamel called Colorado brown stain. (Unknown‚ 2015). The next major development was in the period between 1933-1945 when there was a focus on relationship

Using a cooling glass of water to determine the area and volume of the curve formed. Research Question: To what extent can a cooling glass of water be modelled accurately and be used to find the area under the curve and volume formed by curve? Data Collection: In order to produce an exponentially decaying graph‚ I had to first heat a glass of water for a certain period of time {150 ml of water}. After the water was heated a temperature probe‚ connected to logger pro and laptop

Purpose of lab 1.4 Measuring Volume by Displacement of Water was to determine the fraction of air in different granulated solids. The lab cocised of one test done on four different granular solid; with up to 3 trials on each solid. When all tests are done and put in tables‚ and the calculations are made‚ the conclusion is that grain size does not affect that fraction of air. To be able to find the fraction of air‚ 3 measurement had to be taken‚ the volume of the solid with air‚ the volume of water‚ and

What organic molecule can be detected with Lugol’s? By using the Lugol’s iodine test‚ we can detect the presence of starches. Why put Lugol’s in the beaker and not the bag? When we put the Lugol’s regent (I2Kl) in the beaker‚ we can observe the effects of osmosis as the Lugol’s regent (I2Kl) solution on the outside of the beaker permeates the intestine (Dialysis tubing) inducing a chemical reaction that will turn the liquid in the intestine (Dialysis tubing) blue-black. If the amylase successfully

Qualitative Analysis of Cations Short Overview The most common cations have been placed into five groups based upon solubility in aqueous solutions when different reagents are added. The reactions which occur are useful in identifying the presence of these cations in unknown samples. The process of identifying the cations is called qualitative analysis. The purpose of this experiment is to identify which cations are present in unknown solutions. A data sheet was not prepared for this experiment
