Sažetak
The influence of the pH and other neutral electrolytes upon
the precipitation and hydrolysis of thorium(IV) in aqueous
solutions of thorium nitrate and potassium phthalate was investigated.
A three-dimensional concentration tyndallogram in which
turbidity has been plotted against the concentration of potassium
phthalate and the pH, at constant concentration of Th(IV)
1.25 X 10-3M, shows various precipitation and dissolution regions
of th e system. The following co ncentration regions were marked
and discussed: the concentration region where sudden precipitation
of thorium hydroxide occurs, the region of thorium
hydroxide stable sols, the region of thorium phthalate sols, the
region of unstable systems in which crystals appear after a few
days' aging and the region of stable clear solution at rathe r high
pH values.
The effect of neutral electrolytes upon the precipitation in
the regio n of stable clear solution was investigated. It was d etermined
that neutral electrolytes influence to a great extent
the prec ipitation at the boundary of thorium phthalate precipitate
(pH= 5) .
