Conductivity of Ionic and Molecular Aqueous Solutions Abstract Aqueous solutions that have free ions have higher conductivity values than solutions with most molecules. The purpose of the experiment was to see if ionic strength of an aqueous solution determines its conductivity. We tested each compound by putting the conductivity probe into its aqueous solution. Then the computer would analyze the data and give us a conductivity value. After each solution was tested‚ we used deionized water to

TECH0701: Measuring the Melting Points of Compounds and Mixtures Introduction This exercise dealt with the melting points of pure mandelic acid and benzoic acid. The eutectic temperature and composition of mandelic and benzoic acid mixtures were determined. And finally‚ an unknown was identified by its mixtures and melting point. The melting point of a compound is used by organic chemists not only to identify the compound‚ but also to establish its purity. To determine the melting point two
