A Simple Guide on the Chemical Reactivity of Sodium Bicarbonate with Oxygen

Sodium bicarbonate, sometimes known as baking soda or bicarbonate of soda (IUPAC name: Sodium hydrogen carbonate) is a chemical substance having the formula NaHCO3. It is a salt made up of sodium cation (Na+) and bicarbonate anion (HCO3). 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). Nahcolite is the natural mineral form. It is a constituent of the mineral natron and can be found dissolved in a variety of mineral springs.

Oxygen has an atomic number of 8 and is a chemical element (it has eight protons in its nucleus). At normal temperatures and pressures, oxygen forms a chemical compound (O2) of two atoms, which is a colourless gas. Oxygen atoms are highly reactive and are found in a wide range of typical chemical compounds, including water (H2O), carbon dioxide (CO2), carbon monoxide (CO), sulphur oxides (SO2 and SO3), and nitrogen oxides (NO and NO2).

Chemical reactivity of Sodium Bicarbonate with oxygen

Sodium bicarbonate has no chemical reaction with oxygen. It combines with hydrogen. The hydrogen in an acid (say, vinegar) substitutes the sodium in the bicarbonate to produce hydrogen carbonate, an acid composed of two hydrogen atoms, one carbon atom, and three oxygen atoms.

Decomposition reaction

The decomposition reaction of sodium bicarbonate, often known as baking soda, is an important chemical process in baking because it aids in the rise of baked goods. It is also the method by which sodium carbonate, sometimes known as washing soda, is produced.

Although sodium carbonate, often known as washing soda, undergoes a breakdown reaction, this molecule is more heat-stable than sodium bicarbonate. The reaction’s balanced equation is:

NaHCO3Na2C03+CO2+H2O

Formula of Sodium Bicarbonate

The chemical or sodium hydrogen carbonate is commonly referred to as baking soda. Sodium bicarbonate has the chemical formula NaHCO3. In water, the molecule dissociates into sodium (Na+) cation and carbonate (CO3–) anions. Baking soda is an alkaline white crystalline substance that is often offered in powder form. It tastes slightly salty.

Sodium Bicarbonate and oxygen

Sodium Bicarbonate: Sodium bicarbonate is a white, odourless, crystalline solid or powder that, when exposed to moisture, slowly decomposes to generate sodium carbonate. The compound’s major application is as a food ingredient in both human and animal food items.

Oxygen:  The chemical element with the symbol O and atomic number 8 is oxygen. It is a member of the periodic table’s chalcogen group, a highly reactive nonmetal, and an oxidising agent that generates oxides quickly with most elements and other compounds

Properties of Sodium bicarbonate

Physical properties 

• Sodium bicarbonate has a molecular weight of 84.0066 g/mol and is a white crystalline solid.
• At room temperature, the substance is powdered and has a density of 1.1 to 1.3 g/cm3. The density of sodium bicarbonate in solid form is 2.20g/cc.
• NaHCO3 has a melting point of 50 degrees Celsius and a boiling temperature of 851 degrees Celsius.
• The chemical is water soluble, methanol soluble, and totally immiscible in ethanol.
• A molecule of sodium bicarbonate crystallises to form a monoclinic crystal lattice shape.
• Sodium bicarbonate is a bitter salt with no odour.
• Amphoteric substances include sodium bicarbonate .Furthermore, the molecule has a refractive index of 1.380.

Chemical properties

• Because sodium bicarbonate is alkaline, it combines with acids to generate salt and carbonic acid. Later, the carbonic acid decomposes to generate water and carbon dioxide. 
• When sodium bicarbonate interacts with acetic acid, sodium acetate, water, and carbon dioxide are produced.
• At temperatures ranging from 80 to 100 degrees Celsius, sodium bicarbonate decomposes to generate sodium carbonate, which is then transformed to sodium oxide by additional heating in the presence of oxygen.
• Because sodium bicarbonate has a shelf life of 2 to 3 years when stored in the dark and cold conditions, it will not decompose.

Conclusion

In this article we conclude that the chemical compound sodium bicarbonate, sometimes known as baking soda or bicarbonate of soda, has the formula NaHCO3. It’s a salt made up of sodium cation and bicarbonate anion. Sodium bicarbonate is a white crystalline substance that generally appears as a fine powder. Sodium bicarbonate is an antacid that is used to treat heartburn and acid reflux. In some cases, your doctor may prescribe sodium bicarbonate to make your blood or urine less acidic. This drug is sometimes taken for purposes other than those listed; consult your doctor or pharmacist for further information.
