Sodium bicarbonate is a white crystalline powder (NaHCO3) better known as baking soda. It is classified as an acid salt, formed by combining an acid (carbonic) and a base (sodium hydroxide), and it reacts with other chemicals as a mild alkali. At temperatures above 30068-3 degrees Fahrenheit (149 degrees Celsius), baking soda decomposes into sodium carbonate (a more stable substance), water, and carbon dioxide.
The native chemical and physical properties of baking soda account for its wide range of applications, including cleaning, deodorizing, buffering, and fire extinguishing. Baking soda neutralizes odors chemically, rather than masking or absorbing them. Consequently, it is used in bath salts and deodorant body powders. Baking soda tends to maintain a pH of 8.1 (7 is neutral) even when acids, which lower pH, or bases, which raise pH, are added to the solution. Its ability to tabletize makes it a good effervescent ingredient in antacids and denture cleaning products.
Sodium bicarbonate is also found in some anti-plaque mouth-wash products and toothpaste. When baking soda is used as a cleaner in paste form or dry on a damp sponge, its crystalline structure provides a gentle abrasion that helps to remove dirt without scratching sensitive surfaces. Its mild alkalinity works to turn up fatty acids contained in dirt and grease into a form of soap that can be dissolved in water and rinsed easily. Baking soda is also used as a leavening agent in making baked goods such as bread or pancakes. When combined with an acidic agent (such as lemon juice), carbon dioxide gas is released and is absorbed by the product’s cells. As the gas expands during baking, the cell walls expand as well, creating a leavened product.
In addition to its many home uses, baking soda also has many industrial applications. For instance, baking soda releases carbon dioxide when heated. Since carbon dioxide is heavier than air, it can smother flames by keeping oxygen out, making sodium bicarbonate a useful agent in fire extinguishers. Other applications include air pollution control (because it absorbs sulfur dioxide and other acid gas emissions), abrasive blasting for removal of surface coatings, chemical manufacturing, leather tanning, oil well drilling fluids (because it precipitates calcium and acts as a lubricant), rubber and plastic manufacturing, paper manufacturing, textile processing, and water treatment (because it reduces the level of lead and other heavy metals). Sodium bicarbonate price is depends on its purity and type like sodium bicarbonate food grade or sodium bicarbonate feed grade. Sodium bicarbonate suppliers are offering different prices based on sodium bicarbonate manufacturers.
Buffering: Because of its chemical makeup, Baking Soda has unique capabilities as a buffer. Buffering is the maintenance of a stable pH balance, or acid-alkali balance. As a buffer, Baking Soda tends to cause acid solutions to become more basic and to cause basic solutions to become more acid, bringing both solutions to a stable pH around 8.1 (slightly basic) on the pH scale. A buffer also resists pH change in a solution, in this case maintaining a pH of 8.1. In this way Baking Soda can be used as an antacid in the human digestive system, neutralizing acids from acid indigestion and heartburn and relieving the associated discomfort. (See directions for this use on the Baking Soda box.) When used as a paste on skin or in the bath, Baking Soda soothes the irritation of poison ivy, insect bites, sunburn, and prickly heat. The natural buffering of Baking Soda also means that it’s a safe and natural way to maintain appropriate pH levels in pools, where stable pH keeps water quality at its best, and in septic tanks, where stable pH provides a healthy environment for the beneficial bacteria that break down wastes. Industrially, Baking Soda is used in sewage treatment facilities for its ability to maintain favorable pH levels. Baking soda prices (sodium bicarbonate prices) has been increased in the world during 5 years ago because of high consumption.
Fire Extinguishing: Baking Soda is effective as a fire extinguisher for grease and electrical fires. When Baking Soda is heated it releases carbon dioxide (just as when dough rises) and produces water. Since carbon dioxide is heavier than air and does not support combustion like oxygen does, it smothers the fire while the water that is formed cools the fire to below the ignition temperature. Unlike any other household chemical, Baking Soda both cools and smothers a fire. Many homes have Baking Soda readily available as a first step in fighting kitchen, garage and car fires — then call the Fire Department. Many commercial fire extinguishers, including dry chemical and foam, contain Baking Soda. Sodium bicarbonate food grade is sold more than sodium bicarbonate feed grade in the market.
