Unformatted text preview: For the fourth trial, set up another data table that indicates solution, concentration, and the observations of color change. This color change will occur when test strip is exposed to solution. For the final trial, go back to the first table and record the concentrations of nitrate in the unknown solutions. Data Collection: One chart will contain solely the concentration and source of the nitrate. Another will calculate it’s concentrations in three different units. In the third trial, you are just recording the product of the solutions on the well plate. The fourth trial, you will be observing a color change on the test strip for the concentration level. During each trial the concentrations of nitrate will be measured in different ways. Source Nitrate ion concentration (ppm) Solution Con. Molarity Con. Molality Con. ppm...
