Arthur Dent Posted August 14, 2010 Share Posted August 14, 2010 I have prepared a solution of Nickel Chloride by dropping some Nickel metal shavings in concentrated HCl, and after a few days, the result is a bright, dark emerald green liquid, that still contains a lot of hydrochloric acid. What would be the best way to neutralize the HCl without contaminating the solution with another salt? What i mean to say is the logical choice would be to add some NaOH until I get a 7.0 PH, but it would create unwanted NaCl in my relatively pure solution (I used reagent grade HCl and 99.9% pure Ni). I thought of boiling off the solution but I don't know if I would succesfully drive off all the remaining HCl from my NiCl2. And I don't think that fractional crystallization would work since NiCl2 and NaCl are both highly soluble. Anyway, I have never tried that process. Thanks for any and all advice.

Fuzzwood Posted August 15, 2010 Share Posted August 15, 2010 You could try to use Ni(OH)2. Link to comment Share on other sites More sharing options...
