What bonds do hydrocarbons have?
Aliphatic hydrocarbons are divided into three main groups according to the types of bonds they contain: alkanes, alkenes, and alkynes. Alkanes have only single bonds, alkenes contain a carbon-carbon double bond, and alkynes contain a carbon-carbon triple bond.
Is sodium hydroxide covalent or ionic?
ionic moleculeSodium hydroxide is a white solid. It melts at 318oC and boils at 1390 oC. It dissolves in water to produce a solution that conducts a current. In other words, NaOH is an ionic molecule.
Is mgso4 ionic or covalent?
Magnesium sulfate is an ionic compound as there is a bond between a metal and a non-metal.
Is sodium chloride covalent or ionic?
For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals.
Is sodium sulfate polar or nonpolar?
What types of bonds exist between the atoms in a molecule of sodium sulfate, Na2SO4 ? The formula for this compound can be written as [Na+]2[SO42-], the sulfate anion is formed by covalent bonding between sulfur and oxygen. Since there is a bond polarity to a S-O bond these are polar covalent bonds.
Is sodium sulfate a metal or nonmetal?
Sodium sulfate, also known as NA2SO4 or natriumsulfat, belongs to the class of inorganic compounds known as alkali metal sulfates. These are inorganic compounds in which the largest oxoanion is sulfate, and in which the heaviest atom not in an oxoanion is an alkali metal.Apr 8, 2010
What is sodium acetate?
Sodium acetate is a food additive obtained by neutralization of acetic acid. When used as a food additive, sodium acetate can be indicated by its group name, substance name, or abbreviated name according to the purpose of use. Other purposes (shelf-life extension, combined use with preservative, etc.
What is the formula for sodium sulfide?
The industrial sodium sulfide is mostly a mixture with different numbers of crystalline water. Hence the molecular formula of sodium sulphide is Na2S • nH2O. This sodium sulfide exhibits as yellow or in reddish-brown colour, and it is flaky and granular. It is mainly used in paper, dyes, ore floatation, mineral processing, dyeing industries and printing.
What is sodium sulfide used for?
Sodium sulfide is mainly used in the pulp and paper industry for the kraft process. As in the kraft process, wood is converted into wood pulp, sodium hydroxide and sodium sulfide help to dissolve the lignin of wood fibre.
Is sodium sulfide flammable?
Sodium sulfide is strongly alkaline. It can cause significant skin burns. Reacting with acid can form hydrogen sulfide, which is a highly toxic and flammable gas. In reduced ventilation spaces, hydrogen sulfide accumulates at the bottom. To use hydrogen sulfide, one should keep the safety data sheet with them.
Is sodium sulfide soluble in water?
Sodium sulfide is slightly soluble in alcohol but insoluble in ethers, although the solubility of sodium sulfide depends on the temperature as it is highly soluble. Another main reason behind the solubility of sodium sulfide in water is, it is an ionic compound which tends to disassociate its ions in water.
Overview
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 or Pb salts:
Na2SO4 + BaCl2 → 2 NaCl + BaSO4
Sodium sulfate is unreactive toward most oxidizing or reducing agents. At high temperatures, it …
Forms
• Anhydrous sodium sulfate, known as the rare mineral thenardite, used as a drying agent in organic synthesis.
• Heptahydrate sodium sulfate, a very rare form.
• Decahydrate sodium sulfate, known as the mineral mirabilite, widely used by chemical industry. It is also known as Glauber's salt.
History
The decahydrate of sodium sulfate is known as Glauber's salt after the Dutch/German chemist and apothecary Johann Rudolf Glauber (1604–1670), who discovered it in Austrian spring water in 1625. He named it sal mirabilis (miraculous salt), because of its medicinal properties: the crystals were used as a general-purpose laxative, until more sophisticated alternatives came about in the 1900s.
Physical properties
Sodium sulfate has unusual solubility characteristics in water. Its solubility in water rises more than tenfold between 0 °C and 32.384 °C, where it reaches a maximum of 49.7 g/100 mL. At this point the solubility curve changes slope, and the solubility becomes almost independent of temperature. This temperature of 32.384 °C, corresponding to the release of crystal water and melting of the hydrated salt, serves as an accurate temperature reference for thermometer calibr…
Structure
Crystals of the decahydrate consist of [Na(OH2)6] ions with octahedral molecular geometry. These octahedra share edges such that 8 of the 10 water molecules are bound to sodium and 2 others are interstitial, being hydrogen-bonded to sulfate. These cations are linked to the sulfate anions by hydrogen bonds. The Na–O distances are about 240 pm. Crystalline sodium sulfate decahydrate is also unusual among hydrated salts in having a measurable residual entropy (entro…
Production
The world production of sodium sulfate, almost exclusively in the form of the decahydrate, amounts to approximately 5.5 to 6 million tonnes annually (Mt/a). In 1985, production was 4.5 Mt/a, half from natural sources, and half from chemical production. After 2000, at a stable level until 2006, natural production had increased to 4 Mt/a, and chemical production decreased to 1.5 to 2 Mt/a, with a total of 5.5 to 6 Mt/a. For all applications, naturally produced and chemically pr…
Applications
With US pricing at $30 per tonne in 1970, up to $90 per tonne for salt cake quality, and $130 for better grades, sodium sulphate is a very cheap material. The largest use is as filler in powdered home laundry detergents, consuming approx. 50% of world production. This use is waning as domestic consumers are increasingly switching to compact or liquid detergents that do not include sodium sulfate.
