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
The Solvay process or ammonia–soda process is the major industrial process for the production of sodium carbonate (soda ash, Na 2 CO 3).The ammonia–soda process was developed into its modern form by the Belgian chemist Ernest Solvay during the 1860s. [1]
The term "saleratus" was applied confusingly to both potassium bicarbonate and to sodium bicarbonate (Na HCO 3, what we now call baking soda). [3]: 24–25 Baking soda and cream of tartar were relatively new ingredients for cooks: Soda may have been introduced to American cooking by female Irish immigrants who found work as kitchen help.
The residual sodium carbonate (RSC) index of irrigation water or soil water is used to indicate the alkalinity hazard for soil. The RSC index is used to find the suitability of the water for irrigation in clay soils which have a high cation exchange capacity .
The method is appealing to such users because sodium bicarbonate is widely sold as baking soda, and the temperatures required (250 °F (121 °C) to 300 °F (149 °C)) to convert baking soda to sodium carbonate are readily achieved in conventional kitchen ovens.
Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle of this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as the relative ...
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.

Solution B: 0.8 g of sodium bicarbonate, 7.48 g of potassium chloride and 90 mL of water; Mix Solution A and B and mix 9 mL of the mixed solution to 1000 mL of distilled water. This method to determinate the concentration of bicarbonates and carbonates is also called "Magni's method."
