Barium carbonate is the inorganic compound with the formula BaCO 3. Like most alkaline earth metal carbonates, it is a white salt that is poorly soluble in water. It occurs as the mineral known as witherite. In a commercial sense, it is one of the most important barium compounds. [5]
Sodium hydrogen carbonate (Sodium bicarbonate) – NaHCO 3; Sodium hydrosulfide – NaSH; Sodium hydroxide – NaOH; Sodium hypobromite – NaOBr; Sodium hypochlorite – NaOCl; Sodium hypoiodite – NaOI; Sodium hypophosphite – NaPO 2 H 2; Sodium iodate – NaIO 3; Sodium iodide – NaI; Sodium manganate – Na 2 MnO 4; Sodium molybdate ...
Barium hydroxide ("baryta") was known to alchemists, who produced it by heating barium carbonate. Unlike calcium hydroxide, it absorbs very little CO 2 in aqueous solutions and is therefore insensitive to atmospheric fluctuations. This property is used in calibrating pH equipment.
Its aqueous solution, if clear, is guaranteed to be free of carbonate, unlike those of sodium hydroxide and potassium hydroxide, as barium carbonate is insoluble in water. This allows the use of indicators such as phenolphthalein or thymolphthalein (with alkaline colour changes) without the risk of titration errors due to the presence of ...
As Joe Biden's presidency nears its end, he bid farewell to a "dear friend" in former President Jimmy Carter.. Carter, 100, died on Sunday at his home in Plains, Georgia. Biden released a ...
It is isoelectronic with nitric acid HNO 3. The bicarbonate ion carries a negative one formal charge and is an amphiprotic species which has both acidic and basic properties. It is both the conjugate base of carbonic acid H 2 CO 3; and the conjugate acid of CO 2− 3, the carbonate ion, as shown by these equilibrium reactions: CO 2− 3 + 2 H 2 ...
