What is the difference between sodium bicarbonate and sodium carbonate?

Jar and spoon with baking soda (baking soda).

Baking soda and sodium carbonate are similar, although they have different chemical composition, reactions, and uses. Sodium bicarbonate, known as sodium bicarbonate (NaHCO3), is made up of one sodium atom, one hydrogen atom, one carbon atom, and three oxygen atoms. Sodium carbonate, known as sodium carbonate (Na2CO3), is made up of two sodium atoms, one carbon atom, and three oxygen atoms. In both compounds, sodium separates from carbon when mixed with water, but their responses are different. When sodium bicarbonate decomposes, it oscillates between an acidic and basic state, while sodium carbonate becomes a base, which can be used to neutralize acids.

Baking soda is a common ingredient in cooking. When mixed with water and an acid, it gives off carbon dioxide, which causes baked goods to rise. This effervescent by-product makes baking soda a useful ingredient in carbonated beverages as well. Baking soda has several additional uses; It is a deodorant, a toothpaste ingredient, a cleaning agent, provides relief for thrush and is used to extract venom from insect and jellyfish stings. It can also extinguish small fires, repel ants and cockroaches, and prevent rabbits from eating garden plants.

Baking soda can repel cockroaches.

pH (potential hydrogen) measurements reveal whether a substance is acidic or alkaline, or an acid or base. pH levels are measured on a scale from zero to 14; the lower the number, the more acidic the substance. Pools should have a pH balance in the mid-range, which will allow the chlorine to work effectively without burning the swimmers’ skin or eyes. Sodium carbonate is more alkaline than sodium bicarbonate and is the preferred additive for raising pH levels in swimming pools.

One of the first uses of soda ash was in glass making, which dates back thousands of years to the production of glass in Egypt. Centuries later, glass production is still the main consumer of soda ash. It is also an important ingredient in soaps, detergents, dyes and manufacturing processes. Papermaking uses sodium carbonate to soften the wood particles from the cellulose.

Soda ash can be added to swimming pools to raise the pH level.

Sodium carbonate was originally derived from the ash of burned seaweed, although soda ash can be obtained from the ash of many plants, as well as table salt. In Green River, Wyoming, a prehistoric lake contains about 200 trillion tons of a mineral deposit called trona, which is basically sodium sesquicarbonate. The trona deposit is located between layers of sandstone and shale, and is mined and processed into sodium carbonate. Other natural soda ash deposits can be found throughout the world, including Africa, Asia and the Middle East. Sodium bicarbonate, on the other hand, is not extracted but is a by-product of sodium carbonate production.

Coke can be used to produce soda ash.

Sodium carbonate can also be produced synthetically using the Solvay process, created by a Swiss chemist in the 19th century. Some countries, such as Australia and India, produce soda ash from limestone, salt and coke. Currently, China is the largest producer of soda ash, although the United States follows in second place and competition between the two countries is fierce. Following the US, the main producers are Russia, Germany, India, Poland, Italy, France and the UK.
