Abstract
The influence of constitutive (Agl, l- ions) and nonconstitutive
(Na+ ions) components of silver iodide hydrosols on the transformation
rate of metaphasic silver iodide into crystalline silver iodide
is studied. The simultaneous change of Agl, l - ions, and Na+ ions
concentrations causes a complex change of the value of the constant
k, (which is proportional to the aggregation rate constant k 2).
Within a certain concentration range of constitutive components,
the number of primary particles n 1° is directly proportional to the
concentration of Agl, and the size of primary particles remains
unchanged. Under such conditions, the value of the constant k, is
only affected by the concentration of Na+ ions present in the system.
For relatively high (pl = 1) and relatively low (pl = 4) concentrations
of l- ions the values of the constants k, and b exhibit a
sudden decrease.
