Abstract

Heterogeneous equilibrium have been studied by the method of solubility in the quaternary system: Nickel Nitrate
- Carbamide - Nitric Acid - Water in the temperature of 25 oC.The crystallization ranges of the initial solids are determined:
Nickel Nitrate and Carbamide, eutonic compositions of the ternary systems: Nickel Nitrate - Carbamide- Water and Carbamide -
Nitric Acid - Water, double compounds of Carbamide with Nickel Nitrate in the composition of 10 : 1, 4 : 1 and 2 : 1, Сarbamide
with Nitric Acid in the composition of 1:1, and also two recent coordination compounds, which formed in the reaction system
of acid-base interaction and lead to the formation of two new compounds, containing in its composition simultaneously Nickel
Nitrate, Сarbamide and Nitric Acid.
