PROPERTIES OF SODIUM BICARBONATE

Sodium bicarbonate, commonly known as sodium hydrogen carbonate, has a monoclinic crystalline structure. Nicolas Leblanc, a French chemist, invented sodium carbonate in the year 1791. In 1846, two New York bakers, Austin Church and John Dwight, established the first baking soda plant. It’s a powdered variant of a crystalline white solid chemical compound. This substance, which is used in cooking, is commonly referred to as baking soda. NaHCO3 is its molecular formula. It’s a shaky foundation. The PH level is approximately 8.31.

What is Sodium Bicarbonate

Sodium bicarbonate, also known as sodium hydrogen carbonate, is referred to as baking soda. Sodium bicarbonate has the formula NaHCO3 in its molecular formula. In water, the molecule breaks down into sodium (Na+) and carbonate (CO3–) anions. Baking soda is a powdered, alkaline white crystalline substance. It has a salty undertone to it. Baking soda, together with water and carbon dioxide, decomposes at temperatures above 50 °C (122 °F). The rate of decomposition is affected by temperature, and at normal baking temperatures, it happens quickly.

Structure of Sodium Bicarbonate

One sodium cation and one bicarbonate anion make up a sodium bicarbonate molecule. One atom of sodium, one atom of carbon, one atom of hydrogen, and three atoms of oxygen make up this compound. The lattice structure is monoclinic. The positively charged sodium ion and the negatively charged oxygen form an ionic connection in this situation (which is singly bonded to the central carbon and not bonded to a hydrogen atom). Sodium bicarbonate has 57.1 percent sodium, 27.4% oxygen, 14.3% carbon, and 1.2 percent hydrogen, according to molecular weights.

Properties of Sodium Bicarbonate 

Physical properties: –

A substance’s physical properties are features that may be examined without affecting the substance’s composition or identity. Color, odor, taste, and state of matter are all physical attributes that can be observed in sodium bicarbonate’s appearance. Sodium bicarbonate is a crystalline white powder that can lump. It has a harsh, salty flavor and has no odor. It’s a liquid at room temperature. Solubility is a physical attribute that describes a substance’s capacity to dissolve in water. Water soluble sodium bicarbonate can be isolated from water by evaporation.

Chemical properties: –

Chemical characteristics are observations of a substance that are based on the substance’s ability to modify its chemical makeup. Sodium bicarbonate has two chemical properties: decomposition and ph. pH is a chemical characteristic that refers to the concentration of hydrogen ions (H+) in a solution. The pH scale ranges from 0 to 14, with 0 being the most acidic and 14 being the most alkaline. A pH of less than 7 implies acidity, a pH of 7 suggests neutrality, and a pH of greater than 7 indicates alkalinity. At room temperature, a 1 percent molar solution of baking soda in water has a pH of 8.3. This value shows that baking soda is alkaline, which explains its bitter flavor. Decomposition is the process of breaking down a substance into simpler components that are not the same as the original substance with the help of heat. When heated to over 50 degrees Celsius (122 degrees Fahrenheit), sodium bicarbonate decomposes, or splits apart, into primarily carbon dioxide (CO2) and water (H2O), with trace amounts of sodium carbonate (NaCO3). A chemical change is called decomposition.

CONCLUSION

Sodium bicarbonate is a white crystalline substance that generally appears as a fine powder. It has a somewhat salty, alkaline flavour similar to washing soda (sodium carbonate). It is a constituent of the mineral natron and can be found dissolved in a variety of mineral springs. Nahcolite is the natural mineral form. It is found dissolved in bile, where it serves to neutralise the acidity of the stomach’s hydrochloric acid, and is discharged into the duodenum of the small intestine via the bile duct. It is also synthesised artificially. Sodium bicarbonate is mostly used in cooking (baking), where it combines with other ingredients to produce carbon dioxide, which aids in the rise of dough. Because sodium bicarbonate is amphoteric, it reacts with acids and bases, many laboratories keep a container of sodium bicarbonate powder on hand. It is administered orally as an antacid in an aqueous solution to treat acid indigestion and heartburn. It can also be taken orally to treat chronic forms of metabolic acidosis such chronic renal failure and renal tubular acidosis. Sodium bicarbonate may also be effective in the treatment of aspirin overdose and uric acid kidney stones by urine alkalinization. It is utilised as a therapeutic element in newborn gripe water.
