Insoluble Residue Analysis Equipment
Image shows the equipment typically
necessary to perform analyses for carbonate content by insoluble
residue. Concentrated HCL, which is diluted with distilled water as part
of this analysis, is a strong corrosive irritant. Appropriate personal
protection gear should be worn when handling this chemical; the analyses
should be conducted in a fume hood.
