There are three ways to distinguish between alcohol and white vinegar

1 Use pH test paper, the pH test paper shows that the acidic is white vinegar, and the other bottle is alcohol.

2 Open the cap, fan the cap and put air on it, smell the smell, there is a pungent sour smell of white vinegar.

3 Add the egg shell, and the bubbles are white vinegar.

Generally, white vinegar does not contain alcohol, but there are also some manufacturers who add a small amount of liquor to white vinegar to increase the aroma of vinegar, because the acetic acid in the white vinegar and the ethanol in the alcohol will slowly act to form ethyl acetate, which has a sweet taste.

Adding a little vinegar to the alcohol can later play a role in enhancing the flavor. Moreover, white vinegar and liquor can also have the effect of sterilization and anti-inflammatory. In addition, if you drink a small amount of liquor or liquor with a lower degree, it can dilate blood vessels, improve blood circulation in the body, and reduce cholesterol deposition in the blood.

It is also effective in preventing cardiovascular diseases. Vinegar dissolves calcium and iron in food, making it easier for the body to absorb and protecting the nutrients in food from being destroyed.

Alcohol and white vinegar are mixed to have a certain disinfecting effect. It can kill insects, but the effect is average, and the insecticidal effect is worse than that of drugs. The effect of alcohol and liquor is not the same, liquor belongs to edible alcohol, which is often used for disinfection of household items or environment, but if it is used, it may cause bacterial growth due to starch substances in liquor, so it is not recommended to use liquor for disinfection, and alcohol is usually strictly proportioned into an alcohol solution with a concentration of 75 or 95, the main components are only water and alcohol, and the osmotic pressure of alcohol of 75 can penetrate the surface of bacteria, so that bacterial proteins can coagulate, resulting in bacterial inactivation, to achieve the effect of eliminating bacteria, And the alcohol concentration of 95 is too high, wiping** can cause damage.

Welcome to your consultation, I am the answer to your answer, has helped more than 7,000 people, your question I have seen, is currently sorting out the answer for you, please wait a while

According to your question, make the following answers: If disinfectant alcohol is mixed with white vinegar, it usually has a certain disinfection effect, the main reason is that the alcohol itself is disinfectant, and white vinegar also has a certain disinfection effect. At present, it is recommended to use special disinfectant alcohol for direct disinfection, because after the alcohol is diluted, the disinfection effect will be poor.

The oscillation can feel the density, and the substance that is more like an oily liquid is denser, which is vinegar, and the other is alcohol. The measurement of substances is to use physical methods instead of eating, touching, etc. The first is dangerous, and the second is not a standard answer.

There are many chemical methods, such as pH measurement. In short, there are many chemical methods, and I will not list them all......

Physics: Taste with your tongue, measure density (alcohol is smaller) Chemistry: See who can react with alkali.

Question 1: How to distinguish between liquor and white vinegar? (chemical) take a small amount of each into two groups and put them in two containers.

1. Use the flammability of alcohol Use the fire source close to the surface of the two liquids, and the burning phenomenon is liquor (pay attention to safety). 2. Use acid-base neutralization reaction to add baking soda (NaHCO3, commonly known as face alkali) into the two liquids, and white vinegar is produced by bubbles. Finally, it is not easy to test the results of volatile liquor with a fire source.

Wine and vinegar are neutral and acidic substances respectively, and the results can be known by measuring the pH test paper with pH test paper. If the pH test paper turns red, it is white vinegar because vinegar is acidic. The test paper does not change color is liquor.

Physics) with a smell!

Question 2: How to distinguish liquor, white vinegar and pure water? (Method) Smell according to the smell.

According to the boiling point according to the density.

1. Smell the smell: the white wine is pungent, the water is tasteless, and the white vinegar has a sour taste.

2. Weighing: Take the same volume of three liquids to weigh, the lightest is liquor, the heaviest is white vinegar, and the other is water.

Question 3: How to distinguish between liquor and vinegar Two methods 1Add calcium carbonate (eggs are also OK) to produce bubbles for vinegar.

Question 4: How to distinguish between highly liquor and white vinegar Chemistry White vinegar is mainly an organic acid.

Liquor is an organic acid, ester, alcohol, and many kinds of substances, and you can do targeted tests according to the different substances it contains. For example, the esters heated in the liquor water bath will decompose, and the aromatic smell will be emitted.

Vinegar is sour.

And so on and so forth...

Question 5: How to distinguish white vinegar and liquor in the laboratory? First, it is smell, because the volatile molecules of liquor and white vinegar are different, so the smell is different, so it can be distinguished by smell;

2. Put the same fish bone in the container of liquor and white vinegar, and take it out after a few minutes, the container where the fish bones become soft is filled with white vinegar, because the acid contained in white vinegar will react chemically with the calcium in the fish bones, while wine will not.

Question 6: 3 ways to distinguish liquor from white vinegar 1. Smell: wine has the smell of wine, vinegar and vinegar, and the difference is obvious;

2. Taste: white side shirt laughing wine is spicy, vinegar flavor is sour, and it is very different;

3. Status: Shake or shake the container (bottle), the hops in the liquor bottle will appear, and it is not easy to disappear; The vinegar in the vinegar bottle scatters quickly when shaken.

Question 7: How to distinguish between liquor and white vinegar, at least one chemical method (1) Physical method:

Take a small number of samples and taste them, the one with a sour taste is white vinegar, and the one without a sour taste is liquor. (Also smelled).

2) Chemical Methods:

Take a sample, add soda ash powder (or baking soda), white vinegar is produced if there are bubbles, and liquor is produced without bubbles. (Combustion method can also be used).
