With an acid (commonly used: acetic) CO2 is formed so oxygen from air is excluded in the oxidimetric titration reaction. It otherwise might interfere with the titrant.
Nitro group is electron withdrawing group like the COOH group. But still it is considered to be most easily reducible using a catalyst. As such there are no reports on sodium bicarbonate used directly, however I am using sodium bicarbonate to prevent the catalyst from getting oxidized during the reaction. I have not published the data so far.

Yes, the pancreas produces sodium bicarbonate as part of its role in regulating the pH of the digestive system. Sodium bicarbonate helps neutralize stomach acid that enters the small intestine, creating a more alkaline environment for digestive enzymes to function effectively.
Ammonia plays a crucial role in the Solvay process for manufacturing soda ash (sodium carbonate). In this process, ammonia is reacted with carbon dioxide and water to form ammonium bicarbonate, which then reacts with sodium chloride (brine) to produce sodium bicarbonate. The sodium bicarbonate is subsequently heated to produce soda ash and release carbon dioxide and water. Ammonia is also recycled in the process, making it an integral part of the overall efficiency and sustainability of soda ash production.
In the TCA cycle (Krebs cycle), the conversion of isocitrate to alpha-ketoglutarate is a redox reaction. During this process, isocitrate is oxidized, reducing NAD+ to NADH, while a molecule of CO2 is released. This reaction is catalyzed by the enzyme isocitrate dehydrogenase, highlighting its role in facilitating the transfer of electrons in metabolic pathways.
It works to maintain the pH of the media in an acceptable range by acting as a buffer. see related link
Sodium bicarbonate acts as a chemical leavening agent in baking. When it is combined with an acid (such as vinegar or buttermilk), it releases carbon dioxide gas, which helps the baked goods rise and become more light and fluffy.
When vinegar reacts with baking soda, it produces carbon dioxide gas. If mothballs are present in the vicinity, they may absorb some of this gas. However, the mothballs themselves do not undergo any significant chemical reaction during this process.
Sodium potassium tartrate, also known as Rochelle salt, is a complexing agent in Fehling's solution. It helps to stabilize the cupric ions in the solution and prevents them from precipitating out. This is important for maintaining the reactivity of the solution in detecting reducing sugars through a redox reaction.
Some common salts with sodium include table salt (sodium chloride), baking soda (sodium bicarbonate), and monosodium glutamate (MSG). Sodium is an essential mineral that plays a crucial role in various bodily functions, but consuming high amounts of sodium can be harmful to health.
Calcium carbonate does react with carbonic acid, forming soluble calcium bicarbonate. This reaction occurs in nature when rainwater reacts with limestone. The pH of the solution plays a role in determining the equilibrium of the reaction.
Inorganic metals such as iron and zinc can act as catalysts in reactions by providing a surface for reaction to occur on or by stabilizing reaction intermediates. They can also participate in redox reactions by donating or accepting electrons. Additionally, these metals can form coordination complexes with organic molecules, influencing the reaction pathways and products.
