Trazabilidad residuo químico líquido en laboratorios de docencia Caso: Universidad Colegio Mayor de Cundinamarca, Bogotá D.C, Colombia

Objective: To trace and follow chemical reagents from their initial use to their final disposition in the General Chemistry teaching laboratories at Universidad Colegio Mayor de Cundinamarca, Bogota, D.C- Colombia. Materials and Methods: Laboratory guidelines were reviewed to determine type of reagents for General Chemistry practices and their corresponding volumes. Physical and chemical analyses were subsequently conducted on the identified compounds independent of their level of acidity. Results: Ionic species were identified and attributed to the type of solvent and their solubility properties. Once laboratory practices are completed, reagents continue to react and thereby is of the utmost importance to assure proper storage and handling conditions.
