Soda ash, or sodium carbonate, is used in glassmaking, detergents, cleaning, cooking, and even in swimming pools. It can help remove buildup, increase alkalinity in pools, and control acidity in food. It is also used in pharmaceuticals and can be made from trona or salt water. It is generally safe, but prolonged exposure to dust particulates can be harmful.
Soda ash is the common name for soda ash, a chemical compound frequently used in manufacturing, industry, and even in the home. Glassmaking is one of the main uses of soda ash. Detergents and cleaners can also make use of it and it can also be used in cooking or as a food additive.
Use at home
Sodium carbonate is a natural water softener, making it a common additive to detergents. The products used for these purposes are often sold as washing ash or baking soda. The soda ash prevents hard water from binding to the detergent, allowing it to be more evenly distributed throughout the wash cycle.
Additionally, the compound has demonstrated the ability to help remove buildup. It can help remove alcohol and grease stains from clothing, as well as scale in everything from coffee makers and espresso machines to boilers and water heaters. Running a solution of soda ash and water through these systems from time to time will help prevent mineral buildup in the water and keep them working at their best.
Sodium carbonate can also be used to increase the alkalinity in swimming pools, helping to ensure the correct pH balance of the water. It can be used in dyeing to help the dye bind effectively to the fabric. Photographers also use a soda ash solution as part of the photo development process.
Uses in food and cooking
Some recipes may also call for soda ash, usually as a reactive agent. Many German pretzel recipes, for example, call for lumps of dough to be boiled in a soda-ash mixture before cooking to create an outer shell or crispy crust. Using ash in this way is usually a substitute for lye.
A number of prepared foods and beverages also contain sodium carbonate. It is commonly added to corn syrup, for example, which is a popular sweetening agent. Sodium carbonate can be used as an anti-caking agent, to help baked goods rise, and to help control the acidity of some foods. The compound may also be included in pharmaceuticals, particularly over-the-counter pain relievers.
Use in glass
One of the most common products that can be made with soda ash is glass; more than 50% of all soda ash produced in the world is used for this purpose. When mixed proportionately with sand and calcium carbonate, heated to the right temperature, and then cooled rapidly, the end result is soda-lime silica glass with excellent durability and clarity. This type of glass is in high demand in the automotive and manufacturing industries and can be found in everything from windshields and mirrors to beer bottles.
Industrial and manufacturing uses
Sodium carbonate is also a very common industrial chemical. In addition to food and cosmetics, it is also used in fertilizers. When it comes to exhaust towers and chemical chimneys, this ash can play a very important role in purifying the air because when sodium carbonate reacts with sulfur dioxide and hydrochloric acid, for example, less harmful compounds are produced. .
Chemical formula
Sodium carbonate is known with the chemical formula Na2CO3, referring to the elements that make up its basic composition: Na, which is sodium; C, which is carbon; and O, which is oxygen. However, the Na2CO3 combination is not usually found isolated in nature, so it must be intentionally refined by scientists.
Production
There are two main ways to refine soda ash. Trona, a mineral found in natural deposits in evaporated lake beds around the world, is the most common source. Some salt waters also contain sodium carbonate compounds. To extract the ash, scientists usually subject the trona ore or salt water to various techniques of crushing, heating, spinning, and other techniques.
The compound can also be created in the lab using the Solvay process rather than isolated from existing compounds. Synthetic soda ash usually has the same properties as that found in nature, but can be more expensive to produce. The manufacturing process also creates waste products, including calcium chloride, which can potentially cause pollution.
Safety
Sodium carbonate is generally considered a safe substance. It can be handled without extraordinary precautions, and the United States Food and Drug Administration has deemed it safe for human consumption in all its forms. Those working to extract the compound from raw ore or in laboratories should wear masks, however, as prolonged exposure to any dust particulates can be harmful.
