Question

Describe the manufacturing of baking soda. Why does it lose its activity on long storage?

Answer 1

Answer:

here is ur answer plscheck

Explanation:

Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate), commonly known as baking soda, is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation (Na+) and a bicarbonate anion (HCO3−). Sodium bicarbonate is a white solid that is crystalline, but often appears as a fine powder. It has a slightly salty, alkaline taste resembling that of washing soda (sodium carbonate). The natural mineral form is nahcolite. It is a component of the mineral natron and is found dissolved in many mineral springs.

Answer 2

Answer:

Baking soda/powder is a white crystalline powder.  It comes from what is known now as, Soda ash. Soda Ash is only obtained from mining an ore called trona or through the Solvay process. Trona ore is mined at 1,500 feet below the surface. Since the Solvay process causes alot of pollution, Mining trona is the more efficient way of getting this soda ash even though this way it is much harder to obtain. 

How is it made?

Once trona ore is mined and brought to the surface, it gets transported to a variety of processing plants. Then the ore gets refined into a slurry of sodium sesquicarbonate, which is a soda ash that contains both soda ash(sodium carbonate) and baking soda(sodium bicarbonate)

Now making the baking soda is where it gets difficult. The soda ash is put into a machine that separates the solids from the liquids.  The crystals get dissolved in a bicarbonate solution, made my the manufacturer, in a rotary dissolver, that turns everything into a saturated solution. After, the solution gets filtered to get rid of any non soluble materials and gets pumped through a feed tank at the top of the carbonating tower.  At the bottom of this tower, Carbon dioxide is held under pressure. When our saturated sodium solution moves along in the tower, The carbon dioxide under pressure, cools down and reacts with the solution causing it to turn into sodium bicarbonate crystals. At the very bottom of this machine, the crystals are collected, washed and filtered. They get put into another machine that filters any other liquid that may be in the crystals. Then, these crystals get dried through a dryer called "flash drive" After they're all dried, they get sorted based on particle size and then get cured. Once that one short process is done, everything is ready to be packaged and shipped.

hope so it will help you.
