What is the chemical formula when zinc chloride is dissolved in water and forms tetrahedral chloro aqua complexes where the reduction in coordination number from 6 to 4 further reduces the strength of the O-H bonds in the solvated water molecules ?

You might have to reformulate this question....


We could write the chemical equation for the reaction as follows...

#ZnCl_2(s) + 4H_2O(l) rarr [Zn{(OH)_2}_4]"^(2+) + 2Cl^-#

There might be 4 aqua ligands around zinc, there might be 6. Certainly the zinc complex would have a measurable #pK_a#.
