EFFECT OF DIELECTRIC CONSTANT AND BASICITY ON THE ELECTRODEPOSITION OF NICKEL FROM AMIDE SOLVENTS.

Abstract

This work studies the physical characteristics of nickel electrodeposited from NiCl//2. 6H//2O dissolved in pure formamide, N-methylformamide and N,N-dimethylformamide separately. Experimental results show that N,N-dimethylformamide is a most suitable solvent as compared to N-methylformamide or formamide for deposition of nickel using nickel chloride electrolyte. Boric acid (0. 2M) enhances the hardness more in case of N less than N-dimethylformamide.
