Experiment 18 Chemistry 101 Redox Titration: Determination of the Percentage of Iron in a Sample INTRODUCTION The concentrations of redox-active species can be determined by redox titrations. In a redox titration‚ a measured sample of the unknown is titrated against a standard solution of a substance that will oxidize or reduce the unknown. In the present experiment you will take a sample containing iron‚ add acid to dissolve it [thereby converting all the iron to iron(II)]‚ then

Conclusions: We learned that some nasty stains can come out with some unorthodox products. We used on our stain Isopropyl alcohol (rubbing alcohol)‚ bleach‚ and shout. The product that did the best at pulling out stains was the Isopropyl alcohol. Isopropyl alcohol is a clear‚ colorless‚ flammable‚ mobile liquid‚ (CH3)2CHOH‚ used in antifreeze compounds‚ in lotions and cosmetics‚ and as a solvent for gums‚ shellac‚ and essential oils. It did great job at pulling stains right out of the cloth. This

Solubility Product Determination Purpose • To determine the solubility product constant‚ Ksp‚ of an ionic compound. Introduction The solubility product constant‚ Ksp‚ is a particular type of equilibrium constant. The equilibrium is formed when an ionic solid dissolves in water to form a saturated solution. The equilibrium exists between the aqueous ions and the undissolved solid. A saturated solution contains the maximum concentration of ions of the substance that can dissolve at
