Solubility of Salts: Determining Salt Identity and Temperature-Solubility Relationships
Overview
This lab report documents an experiment investigating the solubility of an unknown salt in water at various temperatures. Through controlled trials involving salt dissolution, evaporation, and mass measurement, the student identified the unknown salt as potassium chloride and calculated its solubility at 20°C to be approximately 66.28g/100g H2O, demonstrating the relationship between temperature and salt solubility.

Abstract
This paper talks about several points in a conducted lab experiment known as the "Solubility of Salts." First, the purpose of the experiment, as well as the methods being undertaken. Next, the materials and methods that were used for the analysis will be discussed. Then, talk about the experiment results, which include the calculations and the raw data (table and chart). Lastly discussed will be the importance of the recorded results and the results obtained when the experiment was conducted. The results of this experiment show the relationship between temperature and solubility of salts when dissolved in water. According to the findings of this paper, the point at which Potassium chloride salt is soluble in water at the point of 200 C is approximately 34.0g/100g of H2O.
Introduction
The purpose of the experiment is to determine the identity and solubility of an unknown salt. The solubility of a substance is an amount at which the substance can be dissolved in any given amount of solvent. The theory behind this experiment is to see how much of a substance, in this case, potassium chloride can be dissolved into another substance, such as water. In a lab report made by a chemistry teacher, Dr. Breinan, he writes, "If you add just a tiny bit of almost any ionic compound to water, it will dissolve. But if you keep adding more and more salt crystals.
