Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate [9]), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO 3. It is a salt composed of a sodium cation (Na +) and a bicarbonate anion (HCO 3 −). Sodium bicarbonate is a white solid that is crystalline but often appears as a
Sodium ascorbate – antioxidant (water-soluble) Sodium benzoate – preservative; Sodium bicarbonate – mineral salt; Sodium bisulfite (sodium hydrogen sulfite) – preservative, antioxidant; Sodium carbonate – mineral salt; Sodium carboxymethylcellulose – emulsifier; Sodium citrates – food acid; Sodium dehydroacetate – preservative
A bicarbonate salt forms when a positively charged ion attaches to the negatively charged oxygen atoms of the ion, forming an ionic compound. Many bicarbonates are soluble in water at standard temperature and pressure; in particular, sodium bicarbonate contributes to total dissolved solids, a common parameter for assessing water quality.

An anticaking agent in salt is denoted in the ingredients, for example, as "anti-caking agent (554)", which is sodium aluminosilicate.This product is present in many commercial table salts as well as dried milk, egg mixes, sugar products, flours and spices.

For example, at room temperature, in a 1-molar solution of acetic acid, only 0.001% of the acid are dissociated (i.e. 10 −5 moles out of 1 mol). Electron-withdrawing substituents, such as -CF 3 group , give stronger acids (the p K a of acetic acid is 4.76 whereas trifluoroacetic acid, with a trifluoromethyl substituent , has a p K a of 0.23).
For example, in the UK, food companies are required to include the "E number(s)" in the ingredients that are added as part of the manufacturing process. Many components of naturally occurring healthy foods and vitamins have assigned E numbers (and the number is a synonym for the chemical component), e.g. vitamin C ( E300 ) and lycopene ( E160d ...
For example, they may be used to treat acidosis due to kidney failure. Used for oral or parenteral therapy, sodium bicarbonate is the commonly preferred alkalinizing agent. [ 1 ] Others include potassium citrate , calcium carbonate , sodium lactate and calcium acetate .
