Síntesis y estudio de soluciones sólidas de KBr y KCl por mecanosíntesis

Abstract

Se sintetizaron y estudiaron soluciones sólidas de KBr y KCl por mecanosíntesis. Las composiciones se calcularon de acuerdo a la estequiometría KBr₁-ₓ Clₓ; x = 0.9, 0.8, 0.7, 0.6, 0.5, 0.4, 0.3, 0.2 y 0.1. La cantidad preparada de los productos fue de 10 gramos. Las concentraciones de Br en los cristales de KCl-KBr se fueron obteniendo mediante la medición de densidades y utilizando la aditividad volúmenes específicos, conocidos como regla Retgers. Las densidades se midieron por un método de pérdida de peso con 1,3-dibromopropano como líquido de flotación. Las composiciones expresadas en porcentaje en moles de KBr en KC1, fueron 1.00, 8.75, 26.64 y 47.84, cada uno con una incertidumbre de ± 0,10 por ciento en moles. Los iones Br se encontraron ubicados al azar en la red de aniones.

The compositions were calculated according to the KBr₁-ₓ Clₓ stoichiometry; x = 0.9, 0.8, 0.7, 0.6, 0.5, 0.4, 0.3, 0.2 and 0.1. The amount of the product prepared was 10 grams. The Br concentrations in crystals of KCl-KBr were obtained by measuring densities and additivity using specific, known volumes as Retgers rule. The densities were measured by a method of weight loss with 1,3-dibromopropane as floatation liquid. The compositions expressed in mole percent KBr KC1, were 1.00, 8.75, 26.64 and 47.84, each with an uncertainty of ± 0.10 mole percent. The Br ions are found randomly located on the network of anions.
