With a pH level of 9, baking soda is one of the most popular—and easiest—ways to alkalize your drinking water. (You also probably already have it in your kitchen.)
However, during the defluoridation process the hydroxyapatite dissolves, and increases the pH and phosphate ion concentration which makes the defluoridated water unfit for drinking. [46] Recently, a ″calcium amended-hydroxyapatite″ defluoridation technique was suggested to overcome the phosphate leaching from hydroxyapatite. [ 46 ]
Cupcakes baked with baking soda as a raising agent. 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 −).
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.

Baking soda is a mainstay in most kitchens, especially if you have a baker in your home. While the essential ingredient is great for making fluffy cakes , muffins , and cookies , it may not be ...
It dissolves in water to give a mildly alkaline solution. It is insoluble in acetone and alcohols. Ammonium bicarbonate decomposes above about 36 °C into ammonia, carbon dioxide, and water in an endothermic process and so causes a drop in the temperature of the water: NH 4 HCO 3 → NH 3 + H 2 O + CO 2. When treated with acids, ammonium salts ...
As water containing carbon dioxide (including extra CO 2 acquired from soil organisms) passes through limestone or other calcium carbonate-containing minerals, it dissolves part of the calcium carbonate, hence becomes richer in bicarbonate. As the groundwater enters the cave, the excess carbon dioxide is released from the solution of the ...
This compound is a source of carbon dioxide for leavening in baking. It can substitute for baking soda (sodium bicarbonate) for those with a low-sodium diet, [4] and it is an ingredient in low-sodium baking powders. [5] [6] As an inexpensive, nontoxic base, it is widely used in diverse application to regulate pH or as a reagent.
