Question

1. Мертвое море содержит около 32% растворенных солей, в основном хлорида магния MgCl2. Укажите, что в данном случае представляет собой а) раствор; б) растворитель; в) решение.​

Answer 1

Composition of the Dead Sea

The Dead Sea is known for its high salt content, containing approximately 32% dissolved salts, primarily magnesium chloride (MgCl2) In this case, let's clarify the terms used in the question:

a) Раствор (solution): A solution refers to a homogeneous mixture composed of a solute dissolved in a solvent. In this context, the dissolved salts in the Dead Sea water make up the solute, while the water itself acts as the solvent.

b) Растворитель (solvent): A solvent is the substance in which a solute is dissolved to form a solution. In the case of the Dead Sea, water serves as the solvent, as it dissolves the salts present in the sea.

c) Решение (dissolved substance): The term "решение" is not commonly used in the context of solutions. However, based on the given options, it can be interpreted as the dissolved substances or solute in the solution. In this case, the решение would refer to the dissolved salts, such as magnesium chloride (MgCl2), in the Dead Sea water.

To summarize, in the case of the Dead Sea, the раствор (solution) refers to the mixture of water and dissolved salts, the растворитель (solvent) is water, and the решение (dissolved substance) is the salts, mainly magnesium chloride (MgCl2)
