In the laboratory, anhydrous sodium sulfate is widely used as an inert drying agent, for removing traces of water from organic solutions. It is more efficient, but slower-acting, than the similar agent magnesium sulfate.
Accordingly, is sodium sulfate an ionic or covalent bond?
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. The attraction of the Na+ cations to SO42- is ionic.
What are the hazards of sodium sulfate?
Toxicological Data on Ingredients: Sodium sulfate anhydrous: ORAL (LD50): Acute: 5989 mg/kg [Mouse]. Potential Acute Health Effects: Hazardous in case of eye contact (irritant). Slightly hazardous in case of skin contact (irritant), of ingestion, of inhalation.
What is the use of sodium sulfate?
Sodium sulfate is mainly used for the manufacture of detergents and in the Kraft process of paper pulping. About two-thirds of the world’s production is from mirabilite, the natural mineral form of the decahydrate, and the remainder from by-products of chemical processes such as hydrochloric acid production.
Why is sodium sulfate used as a drying agent?
Common drying agents are anhydrous inorganic salts that acquire waters of hydration when exposed to moist air or a wet solution. For the most common drying agents such as sodium sulfate or magnesium sulfate, the crystals form larger clumps when they absorb water.
Is na2so4 an acid or a base?
The salts produced from combining strong acids and bases (NaCl, NaNO3, Na2SO4, KCl, KNO3, K2SO4) are neutral salts. If these neutral salts are dissolved in water, the solution pH is close to 7.0. Strong acids react with weak bases, such as ammonia (ammonium hydroxide).
What is sodium sulfite in foods?
Sodium sulfite (sodium sulphite) is a soluble sodium salt of sulfurous acid (sulfite) with the chemical formula Na2SO3. It is a product of sulfur dioxide scrubbing, a part of the flue-gas desulfurization process.
Is na2so4 an ionic or covalent compound?
Compounds that contain both metals and nonmetals are usually ionic. For example, Na2SO4 contains a metal (Na) and nonmetals (sulfur and oxygen), and so is expected to be ionic. NH4Cl is an ionic compound. You might expect it to be molecular because it contains only nonmetals.
What is Glauber’s salt used for?
Glauber’s salt, common name for sodium sulfate decahydrate, Na2SO. 10H2O; it occurs as white or colorless monoclinic crystals. Upon exposure to fairly dry air it effloresces, forming powdery anhydrous sodium sulfate. Johann Glauber was the first to produce the salt (from Hungarian spring waters).
What is the Colour of barium chloride solution?
Barium chloride is the inorganic compound with the formula BaCl2. It is one of the most common water-soluble salts of barium. Like most other barium salts, it is white, toxic, and imparts a yellow-green coloration to a flame.
Definition of decahydrate. : a compound with 10 molecules of water.
How many ions are in sodium sulfate?
Sodium Sulfate is an ionic compound formed by two ions, Sodium Na+ and Sulfate SO−24 . In order for these two polyatomic ions to bond the charges must be equal and opposite. Therefore, it will take two +1 sodium ions to balance the one -2 sulfate ion. This will make the formula for Sodium Sulfate Na2SO4 .
How many ions are there in cacl2?
In CaCl2, the chemical formula tells us that there are two moles of Cl1- in every mole of compound, and three moles of total ions (1 mole Ca2+, 2 moles Cl1-) in every mole of compound.
How many moles of na2so4 are needed?

What is the metallic ion in the compound copper chloride?
The compound CuCl2 is also known as copper chloride. It contains the metallic copper ion and chloride, the chlorine ion. The copper ion has a positive charge of two, whereas the chlorine ion has a negative charge of one.
What does not indicate that a chemical reaction has occurred?
The following can indicate that a chemical change has taken place, although this evidence is not conclusive: Change of odor. Change of color (for example, silver to reddish-brown when iron rusts). Change in temperature or energy, such as the production (exothermic) or loss (endothermic) of heat.
Is Ki an ionic or covalent bond?
First, determine whether the bond is Covalent or Ionic. Ionic: Between a metal and a non metal. In this compound, we have K-Potassium, a metal, and Iodine, a non-metal. Since it is between a metal and a non-metal, it is Ionic.
