with aluminum + barium nitrate + potassium perchlorate + water (in storage), boron + laminac + trichloroethylene. Forms explosive mixtures with lactose, powdered metals (e.g., titanium, antimony, germanium), metal sulfides (e.g., antimony trisulfide, barium sulfide, calcium sulfide, germanium ...
Action of bromine or iodine on a warm concentrated solution of KOH forms bromate and bromide or iodate and iodide, respectively: 3Br2 + 6OH¯→ BrO3¯ + 5Br¯ + 3H2O 3I2 + 6OH¯ → IO3¯ + 5I¯ + 3H2O When carbon dioxide is passed through its aqueous solution and the...
Potassium chromate has oxidative properties, and it can react with the reducing agent in alkaline medium to form Cr(OH)4-(namely CrO?2-). Adding different solutions respectively containing barium ion, lead ion and silver ion to the potassium chromate solution will form the corresponding insoluble...
Bromine trifluoride rapidly attacks the following salts: barium chloride, cadmium chloride, calcium chloride, cesium chloride, lithium chloride, silver chloride, rubidium chloride, potassium bromide, potassium chloride, Potassium iodide, rhodium tetrabromide, sodium bromide, sodium chloride, and sodium iodide...
