متن کاملA Comparative Study of the Polarographic Behavior of Cobalt(II), Nickel(II), Manganese(II), and Zinc(II) in Azide Solutions
O comportamento eletroquímico dos metais cobalto(II), níquel(II), manganês(II) e zinco(II) foi estudado por polarografia em diferentes concentrações do ligante azoteto. As ondas de redução do cobalto(II) e níquel(II) apresentam deslocamento para potenciais mais positivos com o aumento da concentração de azoteto na solução. A antecipação máxima é de 300 mV para o cobalto(II) e de 370 mV para o n...
