  2. Sodium carbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_carbonate

    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. Na 2 CO 3 + 10 H 2 O → Na 2 CO 3 ·10H 2 O. It is one of the few metal carbonates that is ...

  3. Sodium percarbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_percarbonate

    Sodium percarbonate or sodium carbonate peroxide is a chemical substance with empirical formula Na 2 H 3 C 2 O 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 2 CO 3 · 3 H 2 O 2. It is a colorless, crystalline, hygroscopic and ...

  4. Sodium bicarbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_bicarbonate

    Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate [9]), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO 3. It is a salt composed of a sodium cation (Na +) and a bicarbonate anion (HCO 3 −). Sodium bicarbonate is a white solid that is crystalline but often appears as a fine powder.

  7. Water softening - Wikipedia

    en.wikipedia.org/wiki/Water_softening

    In this method, water is treated with a calculated amount of washing soda (Na 2 CO 3), which converts the chlorides and sulphates of calcium and magnesium into their respective carbonates, which get precipitated. CaCl 2 + Na 2 CO 3 → CaCO 3 + 2NaCl. MgSO 4 + Na 2 CO 3 → MgCO 3 + Na 2 SO 4

  9. Natron - Wikipedia

    en.wikipedia.org/wiki/Natron

    Natron is a naturally occurring mixture of sodium carbonate decahydrate (Na 2 CO 3 ·10H 2 O, a kind of soda ash) and around 17% sodium bicarbonate (also called baking soda, NaHCO 3) along with small quantities of sodium chloride and sodium sulfate. Natron is white to colourless when pure, varying to gray or yellow with impurities.
