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...
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 ...
Write a balanced equation for the reaction of potassium carbonate with barium chloride. Precipitation Reaction When two aqueous solutions of ionic compounds are mixed together, the ions dissociate to form new ionic compounds in the solution. However, according to the general solubili...
Write the balanced molecular equation, complete ionic equation, and net ionic equation for the reaction between aqueous solutions of sodium carbonate and barium chloride. Aqueous calcium chloride reacts with aqueous potassium carbonate in a double-displacement rea...
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...
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...
Bromides: Maximum 0.1 per cent. Iodides:Moisten 5 g by the drop wise addition of a freshly prepared mixture of 0.15 ml of sodium nitrite solution, 2 ml of 0.5 M sulphuric acid, 25 ml of iodide-free starch solution and 25 ml of water. After 5 min, examine in daylight. The substance...
Ions which form precipitates with silver nitrate in acid medium, i.e., bromide and iodide, interfere in turbidimetric determinations. It has been proposed that one might precipitate AgCl in the presence of gelatine under exposure to short-wave ultraviolet radiation. The absorbance of the resulting ...
