Barium sulfate groups that are sensitive to overreduction. With a low surface area, the contact time of the substrate with the catalyst is shorter and thus selectivity is achieved. Palladium on barium sulfate is also used as a catalyst in the Rosenmund reduction. As barium compounds emit a green light when burned, barium salts are often used in green pyrotechnic formulas, but the nitrate and chlorate salts are more common. Barium sulfate is commonly used as a component of "strobe" pyrotechnic compositions. As barium sulfate has high burning point and is insoluble in water, it is used as a coating material in
Silver chlorate Silver chlorate Silver chlorate (AgClO) forms white, tetragonal crystals. Like all chlorates, it is water-soluble and an oxidizing agent. As a simple metal salt, it is a common chemical in basic inorganic chemistry experiments. It is light-sensitive, so it must be stored in tightly closed dark-coloured containers. The substance exhibits blasting properties, therefore it is sometimes used as a primary explosive. Silver(I) means silver is in its normal +1 oxidation state. Silver chlorate is produced by the reaction of silver nitrate with sodium chlorate to produce both silver chlorate and sodium nitrate. Alternatively, it may be produced by the transmission
