Hydrolysis equation for CuCl2.

In an aqueous solution of salt, the dissociation process takes place:
CuCl2 = Cu2 + + 2Cl-
HOH = H + + OH-
Let’s compose the hydrolysis equations:
Cu2 + + 2Cl- + HOH = CuOH + + CL- H + + Cl- – molecular equation;
Cu2 + + HOH = CuOH + + H + – shortened equation:
2nd stage:
Cu (OH) Cl + H2O = Cu (OH) 2 + HCl – molecular equation;
CuOH + + Cl- + H2O = Cu (OH) 2 + H + + Cl- – molecular equation;
CuOH + + H2O = Cu (OH) 2 + H + – shortened equation;
The hydrolysis equations show that the medium is acidic, it is created by H + ions, the indicator Pn> 7.
