The absorption of gases in first year chemistry is summarized, such as carbon dioxide, hydrogen chloride, sulfur dioxide, etc.

The pro Oh, if you are a science student, so learning chemistry is very difficult it.

Gas absorption, you just have to determine what kind of gas it is, acidic? Alkaline? Or neutral, and then find and it is the opposite of the liquid to absorb him on it ~ for example, hydrogen chloride, carbon dioxide is an acidic gas, then you use alkaline sodium hydroxide to absorb, if it is ammonia and this kind of alkaline gas, then use acidic sulfuric acid, hydrochloric acid and so on will be able to absorb it. For example, some gases are very soluble in water, such as ammonia, so you can also use water to absorb it.

Chemistry is a science subject that is important to understand, and memorizing it is not a good way to do it.
