Question

Дайте визначення розчину. Наведіть приклади розчинів у природі.

Answer 1

Ответ:Високий уміст розчинених речовин має морська вода. Так, випарюванням 1 л морської води одержують до 35 гморських солей.

Объяснение:розчин це-цілком однорідні суміші з двох (або кількох) речовин, в яких молекули (або іони) одної речовини рівномірно розподілені між молекулами іншої речовини.

Answer 2

Definition of a Solution

A solution is a homogeneous mixture composed of two or more substances. In a solution, the solute is the substance that is dissolved, while the solvent is the substance that does the dissolving. The solute particles are evenly distributed throughout the solvent, resulting in a uniform composition.

Examples of Solutions in Nature

There are numerous examples of solutions in nature. Here are a few:

1. Seawater: Seawater is a solution composed of various dissolved substances. The main solute in seawater is salt (sodium chloride), but it also contains other dissolved minerals, such as magnesium, calcium, and potassium.

2. Air: The air we breathe is a solution of gases. It primarily consists of nitrogen (78%), oxygen (21%), and small amounts of other gases like carbon dioxide, argon, and trace gases.

3. Sugar Water: When sugar is dissolved in water, it forms a solution. The sugar molecules disperse evenly throughout the water, resulting in a sweet-tasting liquid.

4. Brass: Brass is an alloy made by dissolving zinc in copper. The copper acts as the solvent, while the zinc is the solute. The resulting mixture has desirable properties, such as increased hardness and resistance to corrosion.

5. Blood: Blood is a complex solution that contains various dissolved substances, including oxygen, carbon dioxide, nutrients, hormones, and waste products. The plasma acts as the solvent, while the dissolved substances serve as solutes.

These examples illustrate the wide range of solutions found in nature, highlighting their importance in various biological, chemical, and environmental processes.
