Abstract
The effects of electrolytic coagulation of hydrophobic sols of silver halides in statu nascendi by aqueous solutions of sodium pyrophosphate have been investigated. The precipitation system AgNO3-Na4P2O7 shows one maximum. The height of this maximum depends strongly on the concentration of the lattice forming ions. When nitric acid is added and the concentration of AgNO3 is held constant the maximum shifts to higher pyrophosphate concentrations.
