  • Adsorption of Cu(ii) Zn(ii) and Pb(ii) from aqueous

    The Pb(ii)–Cu(ii) Pb(ii)–Zn(ii) and Cu(ii)–Zn(ii) binary aqueous system was prepared by mixing pairs of metal ions with equal initial concentration and the total initial concentrations of the two metal ions were kept in the range of 150 to 1000 mg L −1. 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.

In this redox reaction the Zn(s) is referred to as the reducing agent because it causes the Cu2 to be reduced to Cu. Aug 01 2020 · Cu root-to-shoot translocation efficiency was much lower than that of Zn and Cd or Pb indicating that the strategy of the hyperaccumulator HE S. alfredii to tolerate high Cu largely depends on restriction of Cu in roots which differed from its high tolerance of Zn and Cd by shunting the metals to shoots (Lu et al. 2008 Lu et al. 2013).
