This paper describes the properties of Ni(CF3COO)2-NH4Cl-EtOH solution and nickel deposit from the solution. The properties are compared with those of the electrodeposited nickel from Ni (CF3COO)2-NH4Cl-MeOH bath which were reported in previous paper. Coordination of NH4Cl with Ni2+ was in a molar ratio of 1:2 in the EtOH solution as in the MeOH solution. The current density range for obtaining smooth nickel deposits from the EtOH solution was narrower than that from the MeOH solution. The grain size and hardness of the nickel deposit obtained from the EtOH solution were slightly smaller and harder than those from the MeOH solution. But, the crystal structure of the nickel deposit from the EtOH solution was almost the same as that from the MeOH solution.
