human body. Inorganic material was believed to come from the Earth: salt‚ metals‚ and rock‚ just to name a few. Because of the human’s wonder of natural life‚ organic materials were believed to possess an enigmatic “Vital Force.” Thus organic chemistry was separated from inorganic chemistry‚ and it became it’s own field of science. By the turn of the Nineteenth the “Vital Force” theory was immensely discredited‚ but this branch of science still stayed separated from inorganic chemistry. Back

substances. In ionic compounds valence electrons are transferred from one atom to another‚ resulting in formation of ions of opposite charge. Metals will lose electrons to form cations (positively charged) and non-metals can gain electrons to form anions (negatively charged); these oppositely charged ions attract each other and form an ionic compound Because the attraction of the ions is so strong‚ ionic compounds are always solid at room temperature and usually crystalline with high melting and boiling

Date: 12 March 2014 INTRODUCTION Sodium hexanitrocobaltate (III) is a coordination complex which has the formula Na3[Co(NO2)6]. This compound is yellow in colour. It consists of a central Co3+ ion surrounded by six nitro ligands [1]. This compound is used as a qualitative test for potassium and ammonium ions (so long as certain other cations are not present) [1]. Potassium and ammonium are insoluble in water‚ while sodium is [1]. Hence‚ the potassium and ammonium salts are precipitated as a yellow
