What is lime water about lime water

Calcium hydroxide is a slightly soluble substance, but when carbon dioxide reacts with calcium hydroxide, the dissolution of calcium hydroxide will be reduced, in order to achieve dissolution equilibrium, this will make calcium hydroxide move in the direction of dissolution, carbon dioxide has been reacting with calcium hydroxide, and the product is a precipitate, so as long as there is carbon dioxide, the reaction will continue, so there will be a large number of white precipitate generation.

The solubility of calcium hydroxide is okay, and carbon dioxide reacts with it as a sensitive reaction, so when it encounters carbon dioxide, the phenomenon is so obvious.

The water is transparent, the precipitate is white, and of course it's obvious, because CaCO3 is insoluble in water, and it has nothing to do with the solubility of calcium hydroxide

The clarified lime water becomes turbid, and the amount of precipitation generated is not very large, so it is said to be turbid. If sodium sulfate and barium hydroxide react, it is directly said to form a precipitate. Therefore, "turbidity" is not a phenomenon that requires a large concentration to occur.

Saturated lime water is usually used to test the presence of carbon dioxide, but not to absorb carbon dioxide (sodium hydroxide solution for absorption) because of the low concentration.

caco3 is precipitation! This has nothing to do with concentration.

My chemistry teacher said: don't get into the horns of the horns when learning chemistry, just remember what the teacher taught).

Disrupting the ionization equilibrium as Gaoling 1999 says.

Lime water refers to an aqueous solution of calcium hydroxide, the main component of which is calcium hydroxide that reacts with carbon dioxide to form calcium carbonate and water. Calcium hydroxide is slightly soluble in water, and an appropriate amount of calcium hydroxide is dissolved in water to obtain a clear aqueous solution, commonly known as clarified lime water. Lime water is the earliest cementitious material used by human beings, and it is used to paint walls with lime mortar on buildings, and it has a wide range of applications in civil engineering.

Application of lime.

Lime has a certain bactericidal and insecticidal effect, and the lime slurry containing sulfur powder and other substances is applied to the trees, which can protect the tree, prevent frostbite, and prevent pests from laying eggs.

In agriculture, lime milk and copper sulfate can be used as a pesticide to prepare Bordeaux liquid with bactericidal effect, which has a strong bactericidal ability.

The slurry obtained by adding a large amount of lime to water is lime milk, which can be used for indoor painting. The use of lime paste or slaked lime powder can be formulated into lime mortar or cement-lime mixed mortar, which can be used for plastering and masonry.

<> lime water is generally lime water, which is an aqueous solution of calcium hydroxide, we can mix quicklime and water together, and then filter them with filter paper, so that you can get lime water. Lime water is widely used in civil engineering, and it can also be used to kill pests and bacteria on tree trunks.

What is lime water.

The lime water we usually talk about generally refers to the clarified lime water, which is the aqueous solution of calcium hydroxide. If we have quicklime at home, we can also try to prepare lime water, we only need to inject an appropriate amount of water into the quicklime first.

Then take out the glass rod and use it to stir the quicklime and clean water, and then take out the filter paper and use it to filter the liquid mixed with quicklime and water, so that you can get lime water.
