What is the scientific principle of white vinegar encountering baking soda?

Baking soda is sodium bicarbonate.

White vinegar contains acetic acid, and sodium bicarbonate and acetic acid undergo metathesis reaction to form sodium acetate and carbonic acid, and carbonic acid is unstable and will continue to decompose into carbon dioxide.

and water. Purpose: Baking soda and white vinegar are mixed to produce carbon dioxide gas.

White vinegar is an organic acid, baking soda is sodium bicarbonate, sodium bicarbonate is a strong base, and it is weakly alkaline when dissolved in water. After the two are mixed, sodium bicarbonate and organic acids undergo metathesis reaction, and the generated sodium acetate and carbonic acid can be descaled. When baking soda is mixed with white vinegar, a large amount of carbon dioxide is generated, which gushes out like a volcanic eruption and can extinguish fires.

Baking soda and white vinegar are mixed to produce sodium acetate, carbon dioxide, and water. The chemical equation is: CH3COOH+NAHCo3=CH3COONA+H2O+CO2.

This reaction occurs when the four elementary ions are involved, and the reaction speed is relatively fast, depending on the concentration, temperature, and pH of the substance being mixed. At high pH levels, baking soda reacts to produce sodium carboliter peel acid (Na2CO3) with water. Using the chemical reaction of baking soda and celery white vinegar, it is possible to clean stains, clean kitchen grease, clean faucets, unclog drains, wash toilets, etc.

The chemical reaction of baking soda and white vinegar creates a large number of bubbles that release heat.

The main ingredient of baking soda is sodium bicarbonate, the main ingredient of vinegar is acetic acid, and the chemical reaction equation of sodium bicarbonate and acetic acid is: ch cooh + nahco = ch coona + co + h o. In this chemical reaction, baking soda is dissolved in water to ionize bicarbonate, and acetic acid is more acidic than carbonic acid, so acetic acid and bicarbonate undergo metathesis reaction to generate sodium acetate, carbon dioxide and water hair, and the reaction phenomenon is to produce many colorless bubbles, which look like a volcanic eruption.

The main ingredient of baking soda is sodium bicarbonate, and the ingredient of white vinegar is glycolic acid, and when these two chemicals meet, they will undergo a violent chemical reaction to produce sodium acetate and a large amount of "carbon dioxide" gas and water. Carbon dioxide is getting more and more and more churning in the water, creating a large amount of bubbles.

The magic of baking soda and white vinegar:

1. Clean the neckline stains, the neckline and cuffs of light-colored clothes are very easy to get dirty, and the stains on the neckline and cuffs can be easily cleaned with baking soda and white vinegar. Method: Sprinkle baking soda powder on the neckline or cuffs with stains, put white vinegar into a spray bottle, spray on the baking soda on the clothes, let it stand for half an hour, and wash the clothes normally.

2. Clean kitchen grease, the combination of baking soda and white vinegar can also deal with kitchen dirty grease that is difficult to remove. Method: Sprinkle baking soda on the dirty area, then spray some white vinegar water on it, let it stand for five minutes and then wipe it off with a rag, most of the oil stains can be cleaned and balanced.

3. Clean the faucet, there will be a layer of black stains on the faucet after a long time, and these stains can also be solved with white vinegar + baking soda. Method: Sprinkle baking soda powder on the dark and blackened part of the faucet, then pour some white vinegar on it, wipe it with a paper towel, and the faucet will be completely clean.

4. Dredge the sewer, there will often be residual oil, hair and other things that are easy to clog in the sewer, if it is blocked, you can use baking soda and white vinegar to dredge. Method: Pour the vinegar into the sewer, then pour in the baking soda, wait until the baking soda and the vinegar have a chemical reaction, and the sewer will be unblocked.

5. When washing the toilet and cleaning the toilet, it is also very convenient to use baking soda and white vinegar. Method: Pour baking soda and white vinegar in a 1:2 ratio in an airtight container, pour it on the place that needs to be cleaned when cleaning the toilet, and then brush it with a brush.

The phenomenon after baking soda is mixed with white vinegar: a violent chemical reaction occurs, and a lot of colorless bubbles are produced, like a volcanic eruption.

Baking soda is sodium bicarbonate, and the main ingredient of vinegar is acetic acid. Equation for the reaction of sodium bicarbonate with acetic acid: ch cooh nahco ch coona co h o

Sodium bicarbonate is an acidic salt formed after the neutralization of strong bases and weak acids. It is slightly alkaline when dissolved in water. This property can be used as a starter culture in food preparation. Sodium bicarbonate will remain after the action of sodium carbonate, and excessive use will make the finished product have an alkaline taste.

Sodium bicarbonate is white crystals, or opaque monoclinic fine crystals. Specific gravity 2 15. Odorless, non-toxic, salty, soluble in water, slightly soluble in ethanol. 25 soluble in 10 parts of water, about 18 soluble in 12 parts of water.

The hydrolyzed aqueous solution is slightly alkaline, stable at room temperature, easy to decompose by heat, gradually decomposes at more than 50, completely loses carbon dioxide at 270, has no change in dry air, and slowly deliquescent in humid air.

Phenomenon: A violent chemical reaction occurs, producing many colorless bubbles, like a volcanic eruption.

The main chemical components of baking soda and white vinegar are "sodium bicarbonate" and "acetic acid", respectively, and these two chemicals will undergo a violent chemical reaction when encountered, producing a large amount of "carbon dioxide" gas. More and more carbon dioxide, churning in the liquid substance, will produce a large number of bubbles.

Baking soda must be familiar to everyone, the scientific name is sodium bicarbonate, it is a white powder soluble in water, which can be used to make some pasta, not only In terms of cleaning, the effect of baking soda is also very good, usually baking soda is dissolved in water, and a foreigner does not take the usual path.

Here's the answer to your question: When baking soda (sodium bicarbonate) and white vinegar (acetic acid) are mixed, an acid-base reaction occurs to produce carbon dioxide, water, and sodium acetate. The specific reaction equation is as follows:

NaHCO3 + CH3COOH CO2 + H2O + CH3COONA where NAHC3 is the chemical formula of baking soda, CH3COOH is the chemical formula of acetic acid (acetic acid), CO2 is carbon dioxide, H2O is water, and CH3COONA is the chemical formula of sodium acetate. During the reaction, the bicarbonate ions (HCO3-) in baking soda and the hydrogen ions (H+) in acetic acid combine to form carbon dioxide gas and water. At the same time, the remaining acetate ions combine with sodium ions to form sodium acetate salts.

This reaction produces a large amount of carbon dioxide gas, which causes bubbles to bubble up in the solution of the hail reaction and produce a slight bubbling effect.
