Nickel Treatment By Sodium Hydroxide PPT




Dear Expert,

I was treating a solution of nickel sulphate and nickel chloride with sodium hydroxide and a green ppt. was formed. My problem is- What reaction is taking place? and What is the ppt. formed?

The dissolved nickel is precipitating as nickel hydroxide.

The equation is

NiCl3 + NaOH = NaCl + Ni(OH)3

I believe that Vinod is correct except that the subscript on both sides of the equation should be '2' rather than '3'.
