The product however shows low purity (75pc).  Another also finds that there is no evidence that alkaline diets improve bone health, but suggests that there "may be some value" to alkaline diets for other reasons. Właściwości. His father was the first man to stuff spaghetti with bicarbonate of soda, thus causing and curing indigestion at the same time. 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. The natural mineral form is nahcolite. , Because it has long been known and is widely used, the salt has many related names such as baking soda, bread soda, cooking soda, and bicarbonate of soda. , It is often claimed that baking soda is an effective odor remover,[better source needed] and it is often recommended that an open box be kept in the refrigerator to absorb odor.  Baking soda is commonly added to washing machines as a replacement for water softener and to remove odors from clothes. . Please register to post comments.  This idea was promoted by the leading U.S. brand of baking soda, Arm & Hammer, in an advertising campaign starting in 1972. 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. Wodorowęglan sodu (soda oczyszczona, E500b), NaHCO3 – nieorganiczny związek chemiczny z grupy wodorowęglanów, wodorosól kwasu węglowego i sodu. Z kwasami reaguje z wydzieleniem dwutlenku węgla i wody: Nie reaguje z alkoholami i fenolami, co bywa wykorzystywane do odróżniania ich od kwasów karboksylowych w chemicznej analizie związków organicznych. , It is known as one of the E number food additives E500. Aqueous solutions are mildly alkaline due to the formation of carbonic acid and hydroxide ion: , Saleratus, potassium or sodium bicarbonate, is mentioned in the novel Captains Courageous by Rudyard Kipling as being used extensively in the 1800s in commercial fishing to prevent freshly caught fish from spoiling. The effect is caused by the thermal decomposition, which produces carbon dioxide gas to produce a long snake-like ash as a combustion product of the other main component, sucrose. The modern chemical formulas of these compounds express their precise chemical compositions (which were unknown when the names sodium carbonate and sodium bicarbonate were coined) as sodium hydrogen carbonate (NaHCO3) and sodium carbonate (Na2CO3). Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate), commonly known as baking soda (especially in North America and New Zealand) or bicarbonate of soda, is a chemical compound with the formula NaHCO3. "Myth #100: An Open Box of Baking Soda in the Fridge absorbs Odors", Bruce Weinstein, Mark Scarbrough, Learn how and when to remove this template message, https://www.sciencedirect.com/topics/engineering/mineral-springs, "What's the difference between bicarbonate of soda, baking soda and baking powder? It is a component of the mineral natron and is found dissolved in many mineral springs.  Baking soda is alkaline; the acid used in baking powder avoids a metallic taste when the chemical change during baking creates sodium carbonate. It is a salt composed of a sodium cation (Na+) and a bicarbonate anion (HCO3−). "I want to say, for the benefit of those who are making this investigation," he reported, "that I was told by a judge of a superior court in the mountain country of North Carolina they have discovered a remedy for this disease." As a blasting medium, sodium bicarbonate is used to remove removal surface contamination from softer and less resilient substrates such as aluminium, copper or timber which could be damaged by silica sand abrasive media.. In the midst of the debate on January 26, 1919, Senator Overman interrupted the discussion to announce the discovery of a cure. However, the uranium would wash out with a 2% solution of sodium bicarbonate. DU is not removed by normal laundering; washing with about 6 ounces (170 g) of baking soda in 2 gallons (7.5 l) of water will help to wash it out. The alkaline nature of sodium bicarbonate makes it the only dry chemical agent, besides Purple-K, that was used in large-scale fire suppression systems installed in commercial kitchens.  Since sodium bicarbonate can cause alkalosis, it is sometimes used to treat aspirin overdoses. , It is used in eye hygiene to treat blepharitis.  Many forms of baking powder contain sodium bicarbonate combined with calcium acid phosphate, sodium aluminium phosphate, or cream of tartar. , Some alternative practitioners, such as Tullio Simoncini, have promoted baking soda as a cancer cure, which the American Cancer Society has warned against due to both its unproven effectiveness and potential danger in use. Baking soda may be used together with sourdough, which is acidic, making a lighter product with a less acidic taste. , Although of no practical value, NaHCO3 may be obtained by the reaction of carbon dioxide with an aqueous solution of sodium hydroxide:, Naturally occurring deposits of nahcolite (NaHCO3) are found in the Eocene-age (55.8–33.9 Mya) Green River Formation, Piceance Basin in Colorado. 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: At temperatures from 80-100 °C (176-212 °F), sodium bicarbonate gradually decomposes into sodium carbonate, water, and carbon dioxide. , Intravenous sodium bicarbonate in an aqueous solution is sometimes used for cases of acidosis, or when insufficient sodium or bicarbonate ions are in the blood. The purported cure implied a critique of modern science and an appreciation for the simple wisdom of simple people.  Because baking soda will absorb musty smells, it has become a reliable method for used book sellers when making books less malodorous. , When adding acid, alkaline ingredients such as whole milk or Dutch-processed cocoa are often added to baked foods to avoid an over-acidic taste from the added acid. Wodorowęglan sodu bywa też nazywany kwaśnym węglanem sodu.Ta nazwa może być myląca, gdyż w rzeczywistości wodny roztwór wodorowęglanu sodu ma odczyn słabo alkaliczny i zachowuje się w wielu reakcjach jak słaba zasada.Z kwasami reaguje z wydzieleniem dwutlenku węgla i wody: .
