Sodium Bicarbonate (NaHCO ₃)
Sodium Bicarbonate, commonly known as Bicarbonate of soda. Small white crystal, the solubility of less than sodium carbonate in the water. Is a kind of industrial chemicals, but no toxicity. Solid above 50 ℃ begin to decompose generate sodium carbonate, carbon dioxide and water, and 440 ℃ when the complete decomposition. Sodium bicarbonate is generated after strong base and weak acid and alkali salt, weak alkaline appears when dissolved in water. This feature can make it as a leavening agent in the process of food production. After role in sodium bicarbonate sodium carbonate, use too much will make the finished product has alkali flavor.
Sodium bicarbonate is white crystal, or opaque tiny crystalline monoclinic system. The proportion of 2.15. Odourless, taste salty, soluble in water
, slightly soluble in ethanol. 25 ℃ water soluble in October, when the water soluble in December when he was about 18 ℃. Its aqueous solution is slightly alkaline by hydrolysis, stable in the normal temperature properties, heat decomposition, decomposition gradually in more than 50 ℃, was completely out of co2 at 440 ℃, no change in the dry air, broken down slowly in the moist air.
Manufacturing, selling of kelp taichung litres of birch businesses, in March this year was found to buy industrial baking soda (sodium bicarbonate), ammonium bicarbonate, from September 2012 to January 2015, used to soak seaweed to soften, daily production of about 100 to 200 kilograms of "dirty" seaweed, all eaten by people, taichung district prosecutor office today in violation of food hygiene management operators ancient liter John prosecution.
Is different from the industrial base of soda ash (sodium carbonate) and baking soda (sodium bicarbonate), baking soda is made from soda ash after the crystallization solution or absorb carbon dioxide
Preparing sodium bicarbonate
Preparing sodium bicarbonate
. Baking soda in some places, therefore, also known as the edible alkali (powder). Baking soda in solid state, round, white of color, soluble in water.
Single salt is: normal salt, acid salt, alkali salt, sodium bicarbonate is generated after the strong base and weak acid neutralization acid salt, weak alkaline appears when dissolved in water.
In mass production the food such as steamed bread, and Fried dough sticks, often soda ash of meltwater stir in flour, thermal decomposition into sodium carbonate, carbon dioxide and water, carbon dioxide and water vapor overflow, can cause the food more fluffy, sodium carbonate residue in food. Commonly known as the "alkali buns" such as the north, adding too much soda ash is can taste out.
A gout patients three months ago, stomach cancer surgery, gout attacks, eat not into rice, not to mention colchicine, prednisone, indomethacin...
"I have been afraid of gout attacks a month ago in sodium bicarbonate tablets, two tablets three times a day, or attack, and the stomach."
A lot of gout patients under the guidance of a doctor or other patients, sodium bicarbonate tablets every day 3 to 6 grams. Equivalent to eat 2 to 4 grams of salt, plus a normal diet intake of salt a day 4 to 6 grams, the amount of salt is 6 to 10 grams daily, and then? In the "gout patients ask: salt to eat many affect uric acid?" - sohu health we learn "uric acid sodium + = uric acid sodium single crystal, then the uric acid sodium single crystal precipitation caused by chronic foreign body reaction, surrounded by monocytes and macrophages around, foreign body nodule formation, formation of chronic inflammation. So much salt no increase in blood uric acid, but increase the happening of the tophus. Gout and high uric acid hematic disease patients should eat 4 to 6 grams of salt a day." Sodium bicarbonate is invisible salt, so, gout patients eat sodium bicarbonate must not eat for a long time.
Sodium bicarbonate is not without its merits, it is able to alkalize urine, uric acid in alkaline environment, high solubility, easy from the kidneys. Suggested that gout patients at the time of blood uric acid is high in under the guidance of doctors, the short-term use sodium bicarbonate tablets, blood uric acid decreased to normal range after use.
In daily life, gout patients to eat more alkaline food: alkalize urine, dissolve the uric acid. Alkaline food is not as made of baking soda (sodium bicarbonate) after fermentation pasta, such as steamed bread, steamed stuffed bun, soda biscuit, but fresh vegetables, fruits, milk, nuts, seaweed, etc. Extra water at the same time, should drink 2000 ml to 3000 ml every day, to increase the amount of urine, promote the uric acid eduction, reduce the risk of kidney stones.
