Clay in water dissolves or not. Solubility of various substances

Water is a universal solvent. Because of this, it is never pure. There are always some substances in it. This property of water is used by man for the preparation of various solutions. They are used in all industries, in medicine and even in everyday life. But not all substances are equally soluble in water. Many people will learn about this by experience, someone from special literature or from acquaintances. Especially often asked such a question: "Does clay in water dissolve or not?" This substance is also very common in nature. Clay is often used by man. Many people are also interested in the dissolution of starch, sugar, salt and soda. These are the substances most often used by humans.

What is solubility

The process of dissolution of various substances is the mechanical mixing of their particles with water molecules. This is not only a physical phenomenon, but also a chemical one. When mixing certain substances, chemical reactions may occur. Most often, their ability to dissolve improves with increasing temperature. The property of water to form various mixtures with other liquids, gases and solids a person uses for his own purposes. Most often, solutions are used in cooking: salt and sugar are dissolved to improve the taste of foods, starch and gelatin - to give them a certain consistency, carbon dioxide - to create drinks. The solubility of substances in water is widely used in medicine. For example, for the preparation of various emulsions and suspensions, solutions of medicinal substances and suspensions of insoluble substances for their better effect on the body. It is for this purpose that people often seek an answer to the question of whether clay dissolves in water, because it is used for medicinal purposes.

Features of different solutions

Before answering the question: "Does clay dissolve in water or not?" - it is necessary to understand what will eventually come about. A solution is a homogeneous substance in which the particles of the dissolved substance are mixed with water molecules. Sometimes they become completely invisible, but you can often determine what is in the liquid. Depending on this, all solutions can be divided into several groups.

1. The actual solution, which remains transparent, like water, but has an aftertaste or smell of dissolved substance. So mixed with the liquid salt, sugar, some gases and minerals. This property is often used in cooking.

2. Solutions that acquire not only the taste and smell of the substance, but also its color. For example, water, tinted with potassium permanganate or iodine.

3. Sometimes turbid solutions, called suspensions, are obtained. They are learned about them by those who seek an answer to the question, clay in water dissolves or not. Such solutions can be divided into two groups:

- a suspension in which the particles of matter are evenly distributed between water molecules, for example, a mixture of clay and water;

- an emulsion is a solution of some liquid or oil in water, for example, gasoline.

Does clay dissolve in water

There are substances that are soluble and insoluble. If you experience, you can see that when mixing sand, clay and some other particles with liquid, a cloudy slurry forms. After a while, you can observe how the water gradually becomes transparent. This is due to the fact that particles of sand or clay settle on the bottom. But such solutions also find application. For example, a mixture of clay with water is much better absorbed by the body when taken or when used for masks and compresses. Particles of clay, mixed with liquid, become more plastic and penetrate better through the skin, having a positive effect. The possibilities of clay to treat many diseases have been known for a long time. But it can be used only as a solution of different concentrations. It is for these purposes that people often look for the answer to the question "Does clay in water dissolve or not?"

Dissolving soda, salt and sugar

1. Soda in water is also dissolved mainly for medical purposes. Such mixtures show rinsing the mouth or throat, making lotions or compresses. It is useful to take a bath in a solution of soda. Particles of this substance are completely mixed with water molecules, providing a therapeutic effect on the body.

2. A man uses a salt solution for a long time. It is able to completely dissolve in water. This property is widely used in cooking. More saturated brine solutions are used for rinses and compresses in medicine.

3. Sugar is a substance that also dissolves easily in water completely. This sweet mixture is used in cooking and for the preparation of various medications.

Does the starch dissolve

Clay, soda in water are used a little less often, mainly for medicinal purposes. But starch is a fairly common food product. But, unlike sugar and salt, it does not dissolve in water. It forms a suspension, almost like clay. But these substances have certain differences. Clay and starch dissolve in water identically at room temperature. A slurry forms in which, upon settling, particles of solid matter settle to the bottom. But when the water temperature rises, the starch behaves in a special way. It swells and forms a colloidal solution - paste. This is its property used in the preparation of kissels and various other dishes.

How do most people learn about the solubility of substances

Even in elementary school, children are told about this. Often this is shown to them on illustrative examples. Experiments are carried out in which it is evident that the salt is completely dissolved, and the sand gradually settles to the bottom. The ability of some substances to mix with liquids is checked every day. For example, no one has a question about whether sugar or salt dissolves. But those substances that are used less often, can cause bewilderment. Therefore, people are interested in whether clay and starch dissolve in water, how to properly dilute potassium permanganate, or how to prepare a suspension for compress.
