What is Baking Soda?

S. N. Smith

Baking soda, otherwise known as bicarbonate of soda, sodium bicarbonate, and, less commonly, saleratus, is a chemical salt with diverse practical uses. With a chemical formula of NaHCO3, it is a white powder with crystalline grains. Although it can be produced by artificial means, in its natural form, baking soda is called nahcolite, taking its name from its chemical formula.

Sodium bicarbonate is weakly alkaline. As such, it acts to neutralize acids and break down proteins. This quality accounts for its usefulness as a tenderizer and a leaven. Also, its neutralizing action on acidic scent molecules makes it an effective deodorizer. Added to the water when doing laundry, baking soda stabilizes the pH level, enhancing the detergent’s effectiveness. It may also be added to swimming pool water to balance the pH and keep the water clear.

The most common practical use for baking soda is as a leavening agent in baking. In combination with a liquid and an acid, it undergoes a chemical reaction that releases bubbles of carbon dioxide. Trapped in batter or dough, these carbon dioxide bubbles enable the baked good to rise. Baked goods leavened with baking soda, therefore, generally have a light crumb and are aerated with many holes left by the escaping bubbles of carbon dioxide.

This chemical should not be confused with baking powder, which has added acidifying and drying agents (typically cream of tartar and starch, respectively). It is pure bicarbonate of soda.

Baking soda also has other uses in cooking. A pinch added to tomato sauce while cooking, or coffee while brewing, will reduce its acidity. A small amount added to the soaking water of beans will hasten the softening and cooking processes and reduce the beans’ propensity to cause flatulence in the eater. It's an effective meat tenderizer, and it can be added to stews or rubbed directly on a cut of meat, and then rinsed off before cooking, to make the meat more tender.

When heated, baking soda undergoes a chemical reaction that gives off carbon dioxide, which makes it useful in extinguishing small grease or electrical fires.

Baking soda’s finely gritty texture makes it an excellent, gently abrasive cleaner. It is inexpensive, environmentally friendly, fragrance-free, and safe for nearly all surfaces, making it ideal for household use. As a mild abrasive agent, it can also be used in place of toothpaste. Sprinkled around the exterior entrances to and foundations of homes, it may stop ants and other insects from crawling in, as it is irritating to their chitinous exoskeletons and they usually avoid it.

As an acid neutralizer, baking soda has long been favored for its various first-aid applications. Dissolved into a lukewarm bath, it will soothe the discomfort of sunburn and the itch of poison ivy. Made into a paste with cool water and applied directly to the skin, it will ease the pain of bee stings. One-half teaspoon (2.3 g) mixed into 4 ounces (120 ml) of water can be taken as an antacid. Those taking prescription medications or following a reduced-sodium diet should check with a medical professional before consuming sodium bicarbonate.

Can I, a lady, use baking soda as a panty powder to neutralize odor?

It is my understanding that soda is actually produced in the stomach, so it should be entirely safe. I am not sure if there is a limit to how much one should take. I know it is very dry, so taking more than a tablespoon might be too drying, especially without drinking water with it.

I have been using pure baking soda in my baked goods for a long time. I use roughly the same amount as the recipe calls for in powder, but you will need a tablespoon or so of an acid like lemon juice, vinegar, or buttermilk. I use buttermilk and some water instead of the milk called for in the recipe. Mostly this is workable but people may not feel the goods taste exactly like professionally baked goods but they are certainly edible.

Don't try this. I was experimenting with gargling with peroxide during a temporary sore throat. At the same time, I accidentally mixed baking soda in wheat pancakes, instead of baking powder. Then as I felt funny, I ate some vitamin C (lemon), in order to help the peroxide, which I thought was making me feel funny.

With excedrins I took for a headache also, this all caused a chemical reaction, burning my lips until they were blistered. Took a week of eating low acidic foods to get this under control.

Be careful of mixing chemical releasing agents. Thanks.

Question no. 12: Baking Soda in basically a form of salt, so any 'whitening' effect would be from the temporary white scale left behind from the salts.

anon56853

Not sure how this site works, but, question no. 3 is a really good one. Plants thrive on CO2, therefore adding baking soda to your plant's soil should increase the levels of CO2 available to the plant.

The caveat: baking soda is sodium bicarbonate and therefore will increase the level of 'salt' in the plant's growing medium. Plant roots draw up moisture and nutrients by being 'saltier' than their growing medium, and therefore will not draw up moisture/nutrients as well.

I remember reading an article years ago about pouring milk into the plant's pot and the resulting CO2 discharged being beneficial for this very reason. Hope this helps. Kevlarster, Electrical Engineer
