Can you directly ignite CO gas to experience purity?

Purity testing is the purity of the products tested in chemistry, and purity testing is generally to ensure the safety of chemical experiments. For example, it is necessary to verify the purity before igniting hydrogen, which is a flammable gas. Here's how to verify the purity of hydrogen:

Collect a test tube of hydrogen by exhausting air downward or draining, and block the nozzle with your thumb on the tube filled with hydrogen, with the nozzle facing downward, and immediately move closer to the flame of the alcohol lamp to ignite the hydrogen in the test tube. After ignition, the sound is used to determine whether the hydrogen is pure, and if a sharp popping sound is heard, it means that the hydrogen is not pure and must be re-collected for inspection until a "poof" sound is heard, indicating that the collected hydrogen is pure and ready to use. If the original test tube is still used, you should first block the mouth of the test tube with your thumb for a while, and then collect hydrogen for ignition and purification.

The same goes for CO. Purity inspection requires that the gas used is pure and free of other impurities and gases, otherwise it will affect the experimental effect and endanger the lives of personnel. If the purity of the reactants cannot be guaranteed, the products will not be pure, and the experimental phenomena will be greatly affected.

Before doing the ignition test of combustible gas, it must be purified to avoid the ** caused by impurity of the gas. Therefore, it is necessary to carry out the verification as described above.

No, if the purity is too high, it will not burn completely, causing CO poisoning.

No, if the device can still have air, it may**!

The purity of the gas must be checked first!

No, prevent the device from being caused**.

No, if there is air mixed with it, it will occur at the right concentration (within the limit).

A small amount is passed into the tube (on the book).

It cannot be ignited directly on the generating device to verify purity, and it may occur**. A small portion is collected from a test tube for testing.

General hazardous gases are required, and those that are prone to occurrence need to be purified, such as hydrogen 1) The flammability of carbon monoxide:Phenomenon: Blue flame emitted, exothermic.

In particular, it is pointed out that as with other combustible gases, CO must be a priori pure before it can be ignited. Question:

Why Purification? How to verify purity? Clear:

If co-not. Pure, it may occur when ignited, because the ** limit of CO is the same method of purification as the purity of hydrogen.

The exhaust gas is CO should be CO as a reducing agent, so that the exhaust gas is CO and CO2, CO2 does not support combustion and CO mixing, CO2 is equal to inert gas, so there is no need to test the purity, it is ignited directly, and the purity should be tested when it may be mixed with air.

There is no large amount of mixture of CO and air in the exported gas...

If it is a pure collection of CO and is ready to ignite, it should be a priori pure, because if a certain amount of combustible gas like O2 is mixed into the pure CO, it will happen when it is ignited, so it is better to do a purification test for the sake of safety. The CO that comes with the treatment test is not required. Because the main body in this case is air and not CO, and the amount here is also very small.

Reach the ** limit, this is one of them;

The temperature reaches the ignition point of carbon monoxide, and secondly;

There is enough oxygen to burn, and thirdly;

Space is limited, and that's the fourth.

The ** limit of carbon monoxide mixing with air is ** and does not reach ** limit in air.

I really suspect that you didn't have a serious chemistry in your third year of junior high school, hehe.

At least whether the purity of hydrogen and carbon monoxide should be tested before ignition, the teacher must have said it, hehe.

Yes, yes, yes! Definitely! Definitely!

Unless you have something you can't think about!

Yes, but the method of purification is different from that of other gases.

Want! As long as it can burn, you have to do it!

Need. There are also extreme ......

To test the purity of hydrogen is to see if there is a popping sound when ignited, if there is a popping sound that is not pure, and if there is no popping sound, it is pure.

The prepared flammable gases must be purified, what H2, CO, CH4 and so on.

The purity inspection methods are similar, collect the gas of a test tube, press the nozzle with your thumb, slowly approach the flame of the alcohol lamp, release the nozzle, and hear a crisp popping sound, which is not good.
