Abstract

This paper deals with a simplification in certain quantitative analysis where a production ot precipitation occurs. The purposed tecnique (1) prevents filtrations, and therefore simplifies operations, (2) makes repetitions possible even in the same sample, (3) allows the exact estimation of the volume of the insoluble portion and (4) considers the sensibility of applied instruments.
