Is baking soda toxic?

As people have more and more entertainment options in modern society, many friends like to develop the habit of smoking after work. This not only helps relieve work pressure, but also allows people to indulge themselves for a while. However, long-term smoking can also make teeth turn black and yellow, so many friends like to use baking soda to whiten their teeth. So is baking soda poisonous? Regarding this question, please join me in learning the following content.

Baking soda itself is non-toxic. Its ingredient is sodium bicarbonate, which has a certain alkalinity, but it is very weak. Human gastric juice is acidic. If you put too much in food, it will neutralize with the stomach acid after entering the stomach. This will affect the quality of food digestion and have a slight effect on the human body. It is recommended to put in an appropriate amount.

I've never heard of how toxic soda is.

Sodium carbonate, commonly known as soda, pure alkali, and washing alkali, has the chemical formula: Na2CO3. It is usually a white powder and is a strong electrolyte. The density is 2.532g/cm3,

Sodium carbonate is white powder or granules. Odorless. Alkaline. It is an alkaline salt. It is absorbent. When exposed to air, it gradually absorbs 1 mol/L of water (about 15%). It starts to lose carbon dioxide at 400°C. Decomposes and effervesces when exposed to acid. Soluble in water (3.5 parts at room temperature, 2.2 parts at 35°C) and glycerol, insoluble in ethanol. The aqueous solution is strongly alkaline, pH 11.6. Relative density: 2.53. Melting point 851℃. Median lethal dose (30 days) (mouse, intraperitoneal) 116.6 mg/kg. Irritating. It can be formed by the chemical reaction of sodium hydroxide and carbonic acid.

I believe that through our learning above, most of our friends have their own unique insights and more standard answers to the question of whether baking soda is poisonous. Of course, I would like to remind everyone that baking soda, as sodium hydroxide, not only has the effect of whitening teeth, but also can effectively integrate our stomach acid, so we must clearly understand its various functions so that it can play its role.
