It is also effective in removing heavy tea and coffee stains from cups when diluted with warm water. Also, baking soda can be used as a multipurpose odor remover. During the Manhattan Project to develop the nuclear bomb in the early s, the chemical toxicity of uranium was an issue. Uranium oxides were found to stick very well to cotton cloth, and did not wash out with soap or laundry detergent.

Clothing can become contaminated with toxic dust of depleted uranium DU , which is very dense, hence used for counterweights in a civilian context, and in armour-piercing projectiles. DU is not removed by normal laundering; washing with about 6 ounces g of baking soda in 2 gallons 7.

Sodium bicarbonate is an amphoteric compound. Aqueous solutions are very mildly alkaline due to the formation of carbonic acid and hydroxide ion:. Sodium bicarbonate can be used as a wash to remove any acidic impurities from a "crude" liquid, producing a purer sample. Reaction of sodium bicarbonate and an acid produces a salt and carbonic acid, which readily decomposes to carbon dioxide and water:.

Sodium bicarbonate reacts with acetic acid found in vinegar , producing sodium acetate , water, and carbon dioxide :. Sodium bicarbonate reacts with bases such as sodium hydroxide to form carbonates:. Sodium bicarbonate reacts with carboxyl groups in proteins to give a brisk effervescence from the formation of CO 2. This reaction is used to test for the presence of carboxylic groups in protein.

Most bicarbonates undergo this dehydration reaction. These conversions are relevant to the use of NaHCO 3 as a fire-suppression agent "BC powder" in some dry-powder fire extinguishers. In , French chemist Nicolas Leblanc produced sodium carbonate, also known as soda ash. In , two New York bakers, John Dwight and Austin Church , established the first factory in the United States to produce baking soda from sodium carbonate and carbon dioxide.

Saleratus , potassium or sodium bicarbonate, is mentioned in the novel Captains Courageous by Rudyard Kipling as being used extensively in the s in commercial fishing to prevent freshly caught fish from spoiling. Sodium bicarbonate is produced industrially from sodium carbonate : [70]. Sodium bicarbonate precipitates as a solid from this solution. Regarding the Solvay process , sodium bicarbonate is an intermediate in the reaction of sodium chloride , ammonia , and carbon dioxide.

Although of no practical value, NaHCO 3 may be obtained by the reaction of carbon dioxide with an aqueous solution of sodium hydroxide:. Nahcolite was deposited as beds during periods of high evaporation in the basin.

It is commercially mined using common underground mining techniques such as bore, drum, and longwall mining in a fashion very similar to coal mining. Limited amounts of product are further obtained by solution mining, pumping heated water through previously mined nahcolite beds and reconstituting the dissolved nahcolite above ground through a natural cooling crystallization process.

Sodium bicarbonate, as "bicarbonate of soda", was a frequent source of punch lines for Groucho Marx in Marx brothers movies. In Duck Soup , Marx plays the leader of a nation at war.

In one scene, he receives a message from the battlefield that his general is reporting a gas attack, and Groucho tells his aide: "Tell him to take a teaspoonful of bicarbonate of soda and a half a glass of water. His mother was a well-known bass singer. His father was the first man to stuff spaghetti with bicarbonate of soda, thus causing and curing indigestion at the same time.

How Baking Soda Works - Cooking Chemistry

BBC Food. Cooking Stack Exchange. Into the baking powder mix is an acid, cream of tartar and filler like cornflour to absorb any moisture. It is used for similar foods as sodium bicarbonate. This is an easy one — baking soda is just another name for sodium bicarbonate. The name makes it very obvious what it's used for, so all bakers should have it in their cupboard. The water is evaporated and the resulting slurry is placed into a centrifuge to separate the remaining water from the soda ash crystals.

The crystals are then sent to driers, screened, and sent to storage bins for transport. They use energy and emit toxic VOCs and methane. Trona processing in the U. In eastern Africa, soda ash processing plants have disturbed flamingo populations.

But when you consider that everything has a footprint on this earth and all products come with an intrinsic production cost — and that baking soda is capable of replacing countless other, much worse, lab-contrived substances in our daily lives — it remains a pretty decent option.

In other words, you can go forward in your baking soda-fueled life without feeling terribly guilty. Can't get enough TreeHugger? Sign up now and have it sent straight to your inbox. Daily and Weekly newsletters available.
