Cobalt chloride is used as a humidity indicator, changing from blue to pink as it absorbs moisture. It is also used as a desiccant, in electroplating, as a catalyst for various organic reactions, and as a precursor for synthesizing other cobalt compounds. Additionally, it has uses in laboratory synthesis, such as for making cobaltocene and other organocobalt compounds.  

carbonate powder's uses include acting as a pigment for paints, ceramics, and fireworks, serving as a fungicide and insecticide in agriculture, and being used as an algaecide in swimming pools and spas. It is also used in wood preservatives, as a nutrient in animal feed and fertilizers, and as a catalyst in chemical reactions.
