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
Commercial soda water in siphons is made by chilling filtered plain water to 8 °C (46 °F) or below, optionally adding a sodium or potassium based alkaline compound such as sodium bicarbonate to neutralize the acid created when pressurizing the water with carbon dioxide (which creates high 8-10 pH carbonic acid-bicarbonate buffer solution when ...
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.

The WHO/UNICEF Joint Monitoring Program (JMP) for Water Supply and Sanitation [82] is the official United Nations mechanism tasked with monitoring progress towards the Millennium Development Goal (MDG) relating to drinking-water and sanitation (MDG 7, Target 7c), which is to: "Halve, by 2015, the proportion of people without sustainable access ...
A private-label-brand club soda as seen in Canada. Club soda is a form of carbonated water manufactured in North America, commonly used as a drink mixer. Sodium bicarbonate, potassium sulfate, potassium bicarbonate, potassium citrate, or sodium citrate is added to artificially replicate constituents commonly found in natural mineral waters [1] and offset the acidity of introducing carbon ...
Sodium oxide, an alkali metal oxide; Soda glass, a common glass made with sodium carbonate or sodium oxide; Soda lake, an alternate generic name for a salt lake, with high concentration of sodium carbonates; Soda lime, a mixture of sodium, calcium, and potassium hydroxides; Soda pulping, a process for paper production using sodium compounds
Drinking water quality standards describes the quality parameters set for drinking water. Water may contain many harmful constituents, yet there are no universally recognized and accepted international standards for drinking water. Even where standards do exist, the permitted concentration of individual constituents may vary by as much as ten ...
Piper diagram of water samples from the Mtshabezi River, Zimbabwe. Data source: [2] A Piper diagram is a graphical representation of the chemistry of a water sample or samples. The cations and anions are shown by separate ternary plots. The apexes of the cation plot are calcium, magnesium and sodium plus potassium cations.
