Water is a universal solvent. Because of this, it is never clean. Some substances are always present 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 learn about this empirically, someone from specialized literature or from acquaintances. Such a question is often asked: “Does clay dissolve in water or not?” This substance is also very common in nature. Clay is often used by humans. Many are also interested in the features of the dissolution of starch, sugar, salt and soda. These are the substances most often used by people.
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 can occur. Most often, their ability to dissolve improves with increasing temperature.
Man uses the property of water to form various mixtures with other liquids, gases, and
solids for his own purposes. Most often, solutions are used in cooking: salt and sugar are dissolved to improve the taste of products, 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 best effect on the body. It is for these purposes that people often seek the 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: “Is clay dissolved in water or not?” - you need to understand what should happen in the end. A solution is a homogeneous substance in which particles of a dissolved substance are mixed with water molecules. Sometimes they become completely invisible, but often you can determine what is in the liquid. Depending on this, all solutions can be divided into several groups.
1. Actually a solution that remains transparent, like water, but has an aftertaste or smell of a dissolved substance. So salt, sugar, some gases and minerals are mixed with the liquid . 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 are obtained, called suspensions. They will be found out by those who are looking for an answer to the question whether clay dissolves in water or not. Such solutions can be divided into two groups:
- a suspension in which particles of a substance are evenly distributed between water molecules, for example, a mixture of clay and water;
- an emulsion is a solution of any liquid or oil in water, such as gasoline.
Does clay dissolve in water
There are soluble and insoluble substances. If you conduct an experiment, you can see that when sand, clay and some other particles are mixed with a liquid, a cloudy suspension forms. After some time, you can observe how the water gradually becomes transparent. This is due to the fact that particles of sand or clay settle to the bottom. But such solutions also find application. For example, a mixture of clay and water is much better absorbed by the body when taken orally or when used for masks and compresses.
The clay particles mixed with the liquid become more plastic and penetrate the skin better, exerting their positive effect. The possibilities of clay to treat many diseases have long been known. But you can use it only in the
form of a solution of various concentrations. It is for these purposes that people most often look for the answer to the question “does clay dissolve in water or not?”.
Dissolution of soda, salt and sugar
1. Soda in water is also dissolved mainly for medicinal purposes. Such mixtures are indicated to rinse your mouth or throat, make lotions or compresses. It is useful to take baths in a solution of soda. Particles of this substance are completely mixed with water molecules, providing a therapeutic effect on the body.
2. A person uses a solution of salt for a long time. It is able to completely dissolve in water. This property is widely used in cooking. More saturated saline solutions are used for rinsing and compresses in medicine.
3. Sugar is a substance that is also readily soluble in water completely. This sweet mixture is used in cooking and for the preparation of various medicines.
Does 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 dissolves in water and starch equally at room temperature. A suspension is formed in which, upon settling, particles of solid matter settle to the bottom. But with increasing water temperature, starch behaves in a special way. It swells and forms a colloidal solution - a paste. This property is used in the preparation of jelly and various other dishes.
How most people learn about solubility
Even in elementary school, children are told about this. Often they are shown this with illustrative examples. Experiments are conducted in which it is clear that the salt is completely dissolved, and the sand gradually settles to the bottom. The ability of some substances to mix with liquids is tested every day. For example, no one questions whether sugar or salt dissolves. But those substances that are used less often can be bewildering. 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.
