Benefits:

  • WHAT IS SODIUM CARBONATE? Sodium Carbonate is a sodium salt of carbonic acid and occurs naturally in the burnt ashes of many plants. Sodium carbonate is a strong alkali and forms a strong alkaline solution when dissolved in water, this makes it very useful in industry and is used for many industrial processes today. Sodium Carbonate is commonly known as Soda Ash, Washing Soda or Soda Crystals. Sodium carbonate is a white, anhydrous and hygroscopic powder with a purity of > 99 %.
  • 99.5% SODIUM CARBONATE : Sodium carbonate, also known as soda ash, is a white, anhydrous and hygroscopic powder with a purity of 99 %. There are two forms of sodium carbonate available, light soda and hard soda (granulated). The melting point of sodium carbonate is 851C, it decomposes on heating and therefore the boiling point cannot be determined. Sodium carbonate is an inorganic salt and therefore its vapor pressure can be assumed to be negligible.
  • PROPERTIES OF SODIUM CARBONATE : Sodium Carbonate is a white crystalline powder at room temperature; its melts at 851 C & boils at 1633 C. Sodium Carbonate is odourless and dissolves in water at a rate of 215g/Litre. It remains stable under normal storage conditions & is generally safe to use. Sodium Carbonate (anhydrous) has a density of 2.54 g/cm3 & has a molar mass of 105.98. The pKa of CO3 2- is 10.33, which means that at a pH of 10.33 both carbonate & bicarbonate are present in equal amounts.
  • USES OF SODIUM CARBONATE : Sodium Carbonate is used in Laundry Water Softener, De-scaling, Cleaning Silver, Glass Manufacture, Dyeing, Regulating pH, Electrolysis, Bricks, Casting, Chemistry, Taxidermy and Laundry Detergent etc. Sodium Carbonate softens water by preventing heavy metals from binding to it or the laundry detergent. It's also very effective at removing oil and grease from clothes. Sodium Carbonate can be used to de-scale boilers and kettles.
  • CLEANING SILVER : You can make a cleaning solution by mixing Sodium Carbonate and table salt with warm water. Add some aluminium foil and the silver articles to the cleaning solution and submerge completely. The outer coating of the foil is removed by the solution and an electrolytic cell is formed. The resulting H+ ions reduce the sulphide ions that have formed on the silver and restore its complement.

Description:

Sodium Carbonate is a Sodium Salt of Carbonic Acid. It usually comes in the form of a white crystalline powder. It can be extracted from the ashes of many plants, which is why it is also called soda ash, and it can be produced artificially from seawater and limestone in a brine process. Sodium carbonate has many uses ranging from domestic to industrial or scientific.

How to Use It?

Glass:

The main use of sodium carbonate is in the production of glass. It is mixed with sand and calcium carbonate and heated to very high temperatures and then cooled very rapidly to form glass.

Laundry Detergent:

Sodium carbonate is also known as washing soda because it is one of the main ingredients in most laundry detergents. It acts as a water softener and is good at removing grease, oil and alcohol stains from clothes.

Dyeing:

Sodium Carbonate is also used with some dyes. This helps in properly bonding the dye bond with the fibres of the material.

Regulating pH:

Sodium Carbonate is also used to regulate pH. This has many applications. One of them is to adjust the pH level in swimming pools and make it more alkaline. It is used to develop photographs. It regulates the pH to maintain stable conditions in the mixture of chemicals needed to create the image. It is also used in toothpaste to raise the pH of the mouth. It also works as a foaming agent in the toothpaste.

Electrolysis:

Sodium carbonate is also used as an electrolyte, which helps to create a chemical reaction with the electrodes in a process that involves an electric current and is called electrolysis.

Bricks:

Sodium Carbonate is also used in making bricks. It is used as a wetting agent so less water is needed to make the bricks, reducing the drying time.
