Physical Properties

Sodium carbonate, soda ash, washing soda, or Na2CO3, is a clear water-soluble, odorless compound that has been used for various domestic and industrial uses for a long time. The physical properties of sodium carbonate are particularly interesting to engineers, scientists, and companies who utilize it in various applications, including glass manufacturing and water treatment. In the article below, we’ll examine salt carbonate’s physical and chemical properties in greater detail.

Its Appearance And Texture If It Are Transparent.

White powder with a granular texture. The crystals are huge and are visible under a microscope. It is also hygroscopic, which means it can absorb moisture from the air, which causes it to form clumps and caking.

Melting And Boiling Point

The temperature at which sodium carbonate melts is 851° Celsius (1564 degrees Fahrenheit), while its boiling point is 1633 Celsius (2971 degrees Fahrenheit). The large melting and boiling temperatures enable sodium carbonate to be utilized in industrial processes that require high temperatures, including glass production and the metallurgy industry.

Solubility And Density

Sodium carbonate has an average sensitivity of 2.54 g/cm3, making it denser than water. It is very water-soluble and has a solubility rate of 22.7 at 100 mL of water at temperatures of room temperature. Its high solubility makes it a good choice as a water softener and a cleaning agent.

pH Level

The pH of sodium carbonate is 11.6, which makes it alkaline. This is due to the presence of carbonate ion (CO32-) in its chemical structure. This is why sodium carbonate is commonly employed as a pH-regulating agent in various industrial processes.


Sodium carbonate is composed of several hydrates, such as the decahydrate (Na2CO3*10H2O) as well as the Heptahydrate (Na2CO3*7H2O) and the monohydrate (Na2CO3*H2O). The hydrates form by exposing sodium carbonate air. This is because it easily absorbs water out of the atmosphere. As a result, Decahydrate is widely utilized in household cleaning products.


Sodium carbonate can’t be classified as toxic. However, it is harmful when inhaled or consumed at a high level. It may irritate eyes skin, eyes, and respiratory system. In addition, consumption can cause stomach cramps, nausea, or abdominal discomfort.


Sodium carbonate, or soda ash or washing soda, is a white and inert powder employed in many household and industrial applications. It is extremely alkaline and water-soluble, thus a great cleaning agent and a water softener. In this article, we’ll look at the various uses of sodium carbonate as well as how it can be utilized in various industries.

Cleaning Products

It is important in various cleaning products, such as dishwashing detergents, laundry detergents, and all-purpose cleaners. The alkaline nature of the product helps reduce the breakdown of grease, dirt, and other organic substances, making it much easier to get rid of from surfaces. It also has the property of being a mild abrasive. This means that it can clean dirt without harming surfaces. It is frequently used in conjunction with various cleaning products, such as sodium bicarbonate and sodium percarbonate, to make efficient cleaning solutions.

Water Treatment

The use of sodium carbonate as a water conditioner helps soften hard water, which is water with large amounts of magnesium and calcium ions. These minerals can cause an accumulation of scale in appliances and pipes that could reduce their effectiveness and extend their lifespan. When you add sodium carbonate to soft water, these minerals are dispersed and removed much more quickly. This helps keep the formation of scale in the future.

Glass Production

Sodium carbonate is an essential ingredient in the making of glass. When added to the mixture of ingredients used in making glass, it functions as a flux that reduces the melting point of the mix and allows it to melt more quickly. This lets the glass form to the shape and size you want. It also helps enhance the clarity and durability of the glass.

Paper Production

Sodium carbonate is used in the manufacture of paper as a buffering agent. It aids in controlling its pH and is essential in creating the papers’ quality. It also helps reduce the lignin content in wood pulp, allowing the fibers to break up more easily and creating better quality paper.

Food Industry

The industry of food utilizes it as an ingredient to leaven. For example, when it is combined with acid ingredients like cream of tartar or baking powder, it creates carbon dioxide gas that makes baked goods increase. Sodium carbonate can also be employed to get rid of contaminants from certain foods like cocoa or coffee.


The sodium carbonate compound is used within the field of medicine as a buffering agent and as an excipient. It assists in regulating the pH of specific drugs and may improve their effectiveness and stability. The sodium carbonate can also be used as a filler for certain capsules and tablets.

Sodium Carbonate Vs. Sodium Bicarbonate

Sodium bicarbonate and sodium carbonate are chemical compounds with distinct characteristics and applications.

Sodium carbonate, or washing soda or soda ash, is a chemical with the formula Na2CO3. It is a white, odorless and white powder that is extremely alkaline and dissolves in water. It is employed in the manufacture of soaps, glass, and detergents. It is also used to soften water and as an acid control in swimming pools.

Sodium bicarbonate, or baking soda, is a chemical compound with a formula of NaHCO3. This is white crystal powder that is somewhat alkaline and soluble in water. Sodium bicarbonate is used as a leavening ingredient in baking and as a cleaner for the home and deodorizer. It is also used as an anti-inflammatory to treat the symptoms of heartburn and indigestion.

Sodium Carbonate ph

The pH of the sodium carbonate solution depends on the solution’s amount. For example, a solution of 1% sodium carbonate will have a pH of around 11.6, whereas the solution with 10% has a pH of around 11.0.

Sodium carbonate, or soda ash, is an alkaline compound with a pH above 7. In the presence of water, it is broken down into sodium ions (Na+) and carbonate ions (CO3^2-). The carbonate ions in the solution make the solution alkaline. This implies that the pH is higher than 7.

The pH level of the solution is the determinant of its acidity or basicity, with a pH of 7 being neutral. A pH that is lower than 7 indicates acidity; however, a pH that is higher than 7 is an indication of alkalinity. The pH high of sodium carbonate is a benefit in a variety of applications in the household and industrial, for example, a water softener, cleaning agent, and pH adjuster for swimming pools.
