TITRATED BC Mod. CB-IN-75/EV

DESCRIPTION This kit enables to test different methods for determining , that is molar , , concentration, , 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 , , , nitric acid, with different . 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.
