Constructing a Solubility Curve of Potassium Nitrate
By determining the mass of solute that that can be dissolved in a volume of solvent under a variety of temperatures, we can easily construct a solubility curve. In this lab exercise you will create a solubility curve for potassium nitrate, KNO3.

Jul 1, 2013 · Abstract: My group learned many important lessons from the "Constructing a Solubility Curve Lab". Once we collected data from 3 different temperatures (45 degrees C, 55 degrees C, and 65 degrees C), we confirmed the given theory that solubility increases with temperature increases.

To construct a solubility curve for KNO3 in distilled water. 1. Why does an oil and vinegar salad dressing have two separate layers? 2. When making hot chocolate, how does stirring affect the rate of solvation? 3. How is the solubility of sugar in water affected by increasing the temperature? 4. What does the phrase “like dissolves like” mean? 5.
Constructing a Solubility Curve Procedure: 1) To make a water bath, add approximately 300 ml water to a 400 ml beaker. heat the beaker, with stirring, to either 30 OC, 45 OC, 60 OC, or 75 OC, as agreed to in your pre-lab class discussion. Carefully remove the beaker, using beaker tongs, when it reaches the desired temperature.
In this lab we will examine how much of a particular solute (KClO3) will dissolve in a given amount of water at various temperatures. To determine the solubility of potassium chlorate at a specific temperature. To use the combined class results to produce a solubility curve.

Lab Report: Constructing a Solubility Curve
The purpose of this lab is to collect an experimental data to construct a solubility curve for succinic acid. Significance of lab: After preforming the solubility curve for succinic acid, I was able to understand that as water temperature increases, so does the solubility of a solute.
