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.
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.
2 Νοε 2023 · 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. When it is heated, the water from its structure is removed, forming anhydrous copper (II) sulfate, which is white.
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 xH2O, where x is the number of moles of water per mole of the anhydrous salt.
What is Sodium Sulphate? Sodium sulphate (Na2SO4) is the sodium salt of sulfuric acid. Anhydrous sulphate is a white crystalline solid also known as the mineral thenardite, while the decahydrate Na 2 SO 4.10H 2 O has been known as Glauber’s salt or mirabilis. Na 2 SO 4.7H 2 O is transformed to mirabilite when it is cooled.
A substance that does not contain any water is referred to as anhydrous. Some anhydrous compounds are hydrated so easily that they are said to be hygroscopic and are used as drying agents or desiccants.
24 Νοε 2021 · 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 + CO 2. It can also be prepared by reacting sodium bisulfate with another sodium compound, such as sodium chloride.
