  1. Sodium carbonate decahydrate (Na 2 CO 3 ·10H 2 O), also known as washing soda, is the most common hydrate of sodium carbonate containing 10 molecules of water of crystallization. Soda ash is dissolved in water and crystallized to get washing soda. It is one of the few metal carbonates that is soluble in water.

  2. An oral rehydration solution (250ml) prepared according to WHO formula. Oral rehydration therapy ( ORT) is a type of fluid replacement used to prevent and treat dehydration, especially due to diarrhea. [1] It involves drinking water with modest amounts of sugar and salts, specifically sodium and potassium. [1]

  3. Commercial soda water in siphons is made by chilling filtered plain water to 8 °C (46 °F) or below, optionally adding a sodium or potassium based alkaline compound such as sodium bicarbonate to neutralize the acid created when pressurizing the water with carbon dioxide (which creates high 8-10 pH carbonic acid-bicarbonate buffer solution when ...

  4. Sodium percarbonate, or sodium carbonate peroxide is a chemical substance with formula Na. 2H. 3CO. 6. It is an adduct of sodium carbonate ("soda ash" or "washing soda") and hydrogen peroxide (that is, a perhydrate) whose formula is more properly written as 2 Na. 2CO. 3 · 3 H. 2O. 2.

  5. Sodium sulfate is a typical electrostatically bonded ionic sulfate. The existence of free sulfate ions in solution is indicated by the easy formation of insoluble sulfates when these solutions are treated with Ba 2+ or Pb 2+ salts: Na 2 SO 4 + BaCl 2 → 2 NaCl + BaSO 4. Sodium sulfate is unreactive toward most oxidizing or reducing agents.

  6. Calcium bicarbonate, also called calcium hydrogencarbonate, has the chemical formula Ca (HCO 3) 2. The term does not refer to a known solid compound; it exists only in aqueous solution containing calcium (Ca 2+ ), bicarbonate ( HCO−. 3) ions, together with dissolved carbon dioxide (CO 2 ). The relative concentrations of these carbon ...

  7. Sodium bisulfite solutions can be prepared by treating a solution of suitable base, such as sodium hydroxide or sodium bicarbonate with sulfur dioxide. SO 2 + NaOH → NaHSO 3 SO 2 + NaHCO 3 → NaHSO 3 + CO 2. Attempts to crystallize the product yield sodium metabisulfite (also called sodium disulfite), Na 2 S 2 O 5.
