Sažetak

The literature data concerning the critical coagulation concentration,
Ck, may differ by as much as a factor ten. The
detailed analysis of the changes of various silver iodide sol properties
shows the role of the aging process for characterization
of the system. The ainalysis of the c1c changes and the sedimentation
rates with time and electrophoretic · mobility of •sols containing
sodium, cobalt or lanthanum shows, that the 1sols in presence of
various counter ions have no·t strictly equal colloid properties,
although the counter ions were present at critical coagulation
concentrations.
