TITRATED SOLUTIONS BC Mod. CB-IN-75/EV DESCRIPTION This kit enables to test different methods for determining solution concentrations, that is molar concentration, molality, equivalent concentration, equivalent weight, mass percent, volume percent, grams per liter. Using this kit students will learn to pass from a system to another system applying some transformation formulae. This testing is divided into various sections: the first section consists in preparing dilute solutions starting from concentrated solutions, as well as some solutions of hydrochloric acid, sodium hydroxide, sulfuric acid, nitric acid, with different molar concentration. The second section consists in preparing molar solutions CHEMISTRY using solid solutes: in detail, students will prepare solutions of potassium permanganate and of oxalic acid, with different molar concentration. TRAINING PROGRAM • Learning different methods for determining concentration: molar concentration, molality, equivalent concentration, equivalent weight, mass percent, volume percent, grams per liter • Preparing dilute solutions starting from concentrated solutions - preparing a solution of 1 M of hydrochloric acid - preparing a solution of 0.5 M of sodium hydroxide - preparing a solution of 0.2 M of sulfuric acid - preparing a solution of 0.1 M of nitric acid • Preparing molar solutions from solid solutes - preparing a solution of 0.1 M of potassium permanganate - preparing a solution of 0.5 M of oxalic acid COMPONENTS - Hydrochloric acid - sol. 37% - Sulfuric acid - sol. 96% - Glacial acetic acid - Nitric acid - sol. 65% - Sodium hydroxide - sol. 32% - Ammonium hydroxide sol. 25 % - Oxalic acid - Potassium permanganate crystals -CBIN75-0 - Graduated glassware SUPPLIED WITH THEORETICAL - EXPERIMENTAL HANDBOOK 47A-E-BC ELETTRONICA VENETA S.P.A. - 31045 Motta di Livenza (TV) Italy - Via Postumia 16 - Tel. +39 0422 765 802 - Fax +39 0422 861 901 - E-mail: [email protected] BC 73.
