The investigation of the cation valency influence on cation hydration shell structure was made up. The reliable analysis was made in the framework of the OZ–like integral equations technique and a HNC closure condition. The central force model was used for describing water. The cation $M^{Z+}$ of high valency is modelled as sodium ion with the charge from 1 to 6. The quantitive changes in its hydration shell can be estimated in terms of the running coordination numbers $n_{M\rm O}(r)$ and $n_{M\rm H}(r)$. A significant modification of water intramolecular structure in the hydration shell of ions of high valency was found. An effect of some hydrogen atoms loss from the hydration shell was discovered by means of running coordination numbers. The received results are interpreted as the hydrolysis of water caused by ions of high valency.
