NiCl2 + NaHCO3
NiCO3 + NaCl + HCl
Nickel(II) chloride react with sodium bicarbonate to produce nickel(II) carbonate, sodium chloride and hydrogen chloride. Nickel(II) chloride and hydrocarbonate sodium - concentrated solutions. This reaction takes place at a temperature near 250 and an overpressure, in the atmosphere carbon dioxide.
