Zinc, copper, and lead in midocean ridge basalts and the ...Values of Zn/Pb range from about 100240 and Cu/ Pb from 100156. In this study, Zn is found to correlate positively with TiO2 + FeO (mean square of weighted deviates, MSWD, of for JFR basalt), and inversely with Mg number (MSWD of ). Therefore, contrary to statements in the literature that Zn should be compatible in MORB, Zn is a mildly ...

Order Cu, Mg, Zn and Pb from strongest to weakest | We can summarize this by saying that Zn is a stronger reducing agent than Cu. Part I: The stockroom of the virtual lab contains solutions of Cut2, Mg+2, Zn+2, and Pb+2 ions, and the correspond metals (Cu, Mg, Zn, and Pb). Your first task is to order Cu, Mg, Zn and Pb from strongest to weakest reducing agent.
