    • Abstract

       

      The composition of nickel ferrocyanide was investigated following the amperometric titration of Ni++ up to 40 mM. concentration against potassium ferrocyanide; it appeared to be 3 NiK2 [Fe (CN)6], Ni2 [Fe (CN)6] or Ni5K6 [Fe (CN)6]4. The data showed the possibility of estimating Ni++ polarographically within an experimental error of 1 per cent.
