Can alcohol catch fire when it hits a candle? Is candle fire poisonous when exposed to water?

Yes. Ignition point, oxidizers, combustibles.

Gases, liquids and solid combustibles coexist with air, and when a certain temperature is reached, they will burn spontaneously when they come into contact with the ignition source; The lowest temperature at which the ignition source can continue to burn after the ignition source is removed becomes the ignition point of the substance; The ignition point of alcohol is low, the lower the ignition point, the easier it is to burn, and it will burn when the temperature reaches the spontaneous ignition point; Alcohol is mixed with air at the ** limit.

If you are in range, a little spark can burn.

Precautions for the use of alcohol.

1. Do not use alcohol for large-scale spraying and disinfection of environmental surfaces. For example, corridors, meeting rooms, and offices cannot be disinfected by alcohol spraying.

2. It is not recommended to use alcohol to spray and disinfect clothes, if you encounter open flames or static electricity, combustion may occur.

3. Store alcohol with caution. Keep away from fire and out of easy reach of children.

4. When using alcohol disinfection, it is necessary to ensure ventilation, and it is necessary to stay away from high-temperature objects, and must not be in contact with open flames.

Hello this friend.

If the alcohol touches the candle.

In principle, it will not catch fire.

Unless the candle is lit, the alcohol will definitely catch fire if it touches the candle again.

Look at the concentration of alcohol. High liquor and medical alcohol should be combustible and not otherwise.

Alcohol will definitely catch fire when it touches an open flame.

Summary. Candles are not very poisonous. If you're itchy, there may be something else that's causing it, so you can go to the hospital.

Hello, dear. Candle fire can be poisonous when exposed to water. The main component of the candle is high-grade alkanes, and the main components in the flame are carbon dioxide and water, and the candle will also release lead, mercury and other substances that are harmful to the human body during the burning process.

When the fire of the candle encounters water, it will produce a poisonous substance, and the production will imitate poison.

Is it toxic to humans?

It is also toxic to humans.

Is it poisoned and needs to go to the hospital?

Do you mean that the candle flame touches the surface of the human body when it encounters water?

I didn't touch it, but I felt very itchy on my face.

There will be defenses on the surface of the human body like a brigade, but there is also an upper limit to the defenses. But although this poison of candles exists, it will not hurt much. If you feel very itchy, you can go to the hospital for a look, and there may be other reasons.

Candles are not very poisonous. If you're itchy, there may be something else that's causing it, so you can go to the hospital.

Alcohol is a Class A flammable liquid that burns when exposed to an open flame**.

Please remember that in addition to the ignition point, there is a concept of flash point, and the flash point of ethanol is about 13 degrees, indicating that ethanol is extremely flammable and dangerous!

The ignition temperature of pure ethanol is 363 degrees Celsius, and the ignition temperature is measured under the standard case, which is used as a reference value for the spontaneous ignition temperature, because the spontaneous ignition temperature is not fixed due to the actual situation (the spontaneous ignition point is that there is no external ignition source, and it burns by itself, and it is divided into heated spontaneous combustion and self-heating spontaneous combustion). The ignition point of pure ethanol is 75 degrees (the ignition point is the lowest temperature at which the external heat source needs to be ignited, and the heat source can continue to burn after the heat source is removed), the lower the ethanol concentration, the higher the ignition point. (You should usually note that the higher the concentration of liquor, the easier it is to ignite, and the lower concentration liquor needs to be heated to ignite).

12 degrees Celsius is the flash point of ethanol.

There is no open flame as long as it reaches a certain temperature (in the presence of oxidant), but paraffin wax does not have a fixed ignition point, generally around 158 degrees Celsius.

To explain this problem, first state what an open flame is. An open flame is actually a phenomenon of steam combustion. For example, paraffin wax vaporizes into paraffin vapor at high temperatures, and the flame can be seen when it burns.

Some substances that are more difficult to vaporize, such as graphite, do not have a flame when burned. Therefore, whether to burn or not has nothing to do with the flame, only with the temperature.

Here's an explanation of why paraffin wax doesn't have a fixed ignition point. Paraffin is a mixture of higher aliphatic hydrocarbons and has no fixed chemical formula. Therefore, the ignition point will also change due to different compositions, and generally only one range of changes can be given for reference.

Yes, as long as the ignition point is reached, there is oxygen**.

The main determinant of candles is paraffin. The number of carbon atoms in paraffin wax is generally 22-36, the molecular weight range is 360-540, and the boiling point is 300-550 degrees. Paraffin ignition point 188

However, the candle is a mixture, and the ignition point itself is not fixed.
