Lead chrome green is the main coloring pigment in coating industry, and most green paints are made with this pigment. In addition, it is also used in paints and plastics. Its application range is very similar to that of lead chrome yellow. Due to the chromium yellow in the composition, attention should be paid to the toxicity of lead. Lead chrome green contains iron blue and lead chromate as oxidant.
Chromic acid is the most common cleaning solution used in the laboratory. It has both acidity and oxidizability. It can remove the dirt and insoluble substances on the inner and outer walls of experimental instruments.
