Sažetak
The behaviour of the four-component system: gelatin-FeC13 - NaCl (neutral electrolyte) - pH (HCl or NaOH) was investigated. The regions of the gel formation, of the precipitation of brown Fe(OH)3 flocks , of flocks and gel appearing together, and of the clear solution, were investigated and represented on a threedimensional diagram (Fig. 13.). The gelatin concentration was kept at the constant value of 0.4250/o, but the concentra tions of FeCl3,
the concentrations of NaCl and the pH values were varied and used as coordinates on Fig. 13.
