Abstract
Optimal conditions for the homogeneous precipitation of lead
chlorofluoride were investigated and the method was compared
with the classical procedure. The most suitable reagent for the
pH control of the homogeneous solution was found to be urea \\'.ith
ammonium acetate buffer. If the precipitate obtained by both
procedures was allowed to stand overnight, homogeneous precipitation
resulted with more accurate data.
