Sažetak
The system FeC13-NaCl-NaOH is one of the simpler systems
composing the four component system gelatin - FeC1 3-NaC l-HCl
or NaOH. It is formed by addition of the NaCl component to the
system FeC1 3-NaOH. The precipitation curve of the system FeC1 3-
-NaCl-Na OH consists of only one maximum. The coagulating action
of 6 · 10-1 N NaCl causes the joining of two separate maxima occurring
in the system with no NaCl added. The summary diag r ams represent the regions of the precipit ation curve in dependence -on the concentrations of the FeC 13 and NaOH components and the corresponding pH values. At certa in concentrations of the FeC 13 component, the precipitation maximum is extended far into the positive (acid) s ide.
