ABSTRACT

A practical itemsolutions and colloids in the chemistry lab at the University of Amazonia was conducted was carried out in order to establish features in some of its physical properties and classify them consideringthe type of mixture formed as solutions or colloids according to the nature of the solute and electrolyte or non-electrolyte .

The instruments we use to practice were: the graduated pipette 10test tubes, test tube clamp, glass rod , spatula, macropipeteador and laser pointer. The practice in the laboratory allowed us to know the characteristics and physical properties of the mixtures.

Thepractice was carried filling data tables, which were necessary to establish how much amount is added to the mixture. Data on average error is found through established formulas and calculator.

Uponcompletion of practice it was found that mixtures were colloid and which are not given in these solutions used.

RESUMEN

Se realizó una práctica con el tema soluciones y coloides en ellaboratorio de química de la Universidad de la Amazonia, se llevó a cabo con el fin de establecer características en algunas de sus propiedades físicas y clasificarlas teniendo en cuenta el tipo de mezclaformado como soluciones o coloides según la naturaleza del soluto como electrolíticas o no electrolíticas.

Los instrumentos que usamos para la práctica fueron: la pipeta graduada, 10 tubos de ensayos,pinza para tubos de ensayo, varilla de vidrio, espátula, macropipeteador y apuntador laser. La práctica en el laboratorio nos permitió conocer las características y propiedades físicas de las...
