Tubino Química PAR zinc copper kinetics mechanism The kinetics and mechanism of the reactions between 4-(2-pyridylazo)-resorcinol and Zn2+,Cu2+ and Zn2++Cu2+ equimolar mixtures were studied. The reactions were performed in aqueous solution(pH = 8.5, borate buffer) and monitored spectrophotometrically at 500 nm using stopped-flow technique.Spectral and kinetic data indicate that the Zn2++Cu2+ equimolar mixture behaves as an unique speciesand it can be attributed to the interactions of Zn2+ and of Cu2+ with water molecules in the aqueoussolution. A mechanism is proposed and the rate constants are calculated. 2003 artículo científico 0100-4670 https://www.redalyc.org/articulo.oa?id=42928107 en http://www.redalyc.org/revista.oa?id=429 Eclética Química application/pdf Universidade Estadual Paulista Júlio de Mesquita Filho Eclética Química (Brasil) Num.1 Vol.28
