摘要：

Alkali metal chlorides in the concentration range 0.006-4M influence the solubility, crystal form and filterability of precipitated, tetraphenylarsonium perchlorate. Low salt concentrations increase, and high concentrations decrease the filterability and solubility. The mean activity coefficient of tetraphenylarsonium perchlorate is controlled by general and specific salt effects. Crystal nucleation is probably heterogeneous in low concentrations of salt and homogeneous in high concentrations. © 1969.
