  1. Anhydrous, it is a white crystalline solid of formula Na 2 SO 4; the decahydrate Na 2 SO 4 ·10H 2 O has been known as Glauber's salt or, historically, sal mirabilis since the 17th century. Sodium sulfate is mainly used for the manufacture of detergents and in the Kraft process of paper pulping.

  2. Chemical properties. 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: Na2SO4 + BaCl2 → 2 NaCl + BaSO4.

  3. 24 Νοε 2021 · Sodium sulfate occurs naturally as the minerals thenardite (anhydrous Na 2 SO 4) and mirabilite (Na 2 SO 4 ·10H 2 O). Both forms appear depending on the weather conditions. Preparation. Sodium sulfate can be prepared by reacting a sodium salt or hydroxide with sulfuric acid or another soluble sulfate. Na 2 CO 3 + H 2 SO 4 → Na 2 SO 4 + H 2 O ...

  4. 2 Νοε 2023 · Salts that contain water within their structure are called hydrated salts. Anhydrous salts are those that contain no water in their structure. A common example is copper (II) sulfate which crystallises forming the salt hydrated copper (II) sulfate, which is blue.

  5. 17 Ιουν 2023 · A hydrate contains a definite number of water molecules bound to each ionic compound (also called the anhydrous salt). The formula of the hydrate is represented by the formula of the anhydrous salt followed by a dot and x H 2 O, where x is the number of moles of water per mole of the anhydrous salt. The hydrate is named by naming the anhydrous ...

    Formula of a Hydrate (\(\text{Anhydrous Solid}\ce{*}x\ce{H2O}\)) The formula of a hydrate can be determined by dehydrating a known mass of the hydrate, then comparing the masses of the original hydrate and the resulting anhydrous solid.
