Reprecipitation during the preparation of demineralized sections. II. Experimental observations
Abstract:
Teeth were incompletely demineralized by immersion in unchanged 10% formic acid for 7 days. Reprecipitation deposits of secondary calcium phosphate were present in the dentin and soft tissues of the dental pulp and, if the final pH was 3 or greater, in the remnants of the periodontal ligament. The deposits in the dentin appeared to be intratubular. Deminieralized sections of teeth suspended in supersaturated solutions of brushite contained similar deposits in the soft tissues. It is suggested that reprecipitation of secondary calcium phosphates is a frequent intermediate stage during demineralization with formic acid.

Precipitation Gravimetry
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...
