After the article about baking soda Many remind me that soda is necessary to extinguish.
Let us recall the chemistry for 9 grade school? Soda quenched with acid. The result is a pop. If, for example, to mix the citric acid with soda, the obtained solution with bubbles of carbon dioxide. Due to such a cheerful bubble drink is pleasant to drink. Furthermore cheerful bubbles will pop sodium citrate. It is sometimes used for diseases of the urinary tract.
And what happens if you add baking soda in hot water? They will also get blisters. Sodium bicarbonate is converted to sodium carbonate (soda ash). Will release carbon dioxide. This process starts at 60 degrees and faster at higher temperatures. That is why when baking the dough in the oven for baking soda raises.
Think hot soda solution will be less aggressive? Not! On the contrary! A solution of soda ash has a higher pH. Soda ash is added to the detergent. With soda washes yellow armpit on T-shirts. This caustic solution is more and more strongly irritates the stomach.
Soda has a Hazard Class 3, that is, it is classified as moderately hazardous substances. Baking soda has no class, no danger to health, requires precautions.
Soda is not quenched in hot water. In hot water, baking soda release carbon dioxide and soda ash is obtained. Soda - a means for washing. Why take her in?
Let us once and repeat for the third time. Baking soda in solution exhibits moderate alkaline properties. When heated, it loses its delicate and necessary to us in the body bicarbonate. Bicarbonate is converted to carbon dioxide and water. Remains coarse soda ash, which is considered hazardous to health. That is, by heating baking soda lye disappears in it. Just part alkali decomposes into carbon dioxide and water. The remaining alkali in this case becomes more corrosive.
