Question

In which of the solvent water kerosene and cooking oil does the coal powder dissolve?

Answer 1

Coal cannot be dissolve in any of the solvent.

Answer 2

Answer:

Solvents such as kerosene,water and cooking oil don't dissolve coal powder in them.

hydrocarbons (petroleum, gasoline, gasoline, etc.) simply do not dissolve in water. This is because like dissolves like.

Also, kerosene is lighter than water and floats on its surface rather than dissolving. That is why they are called immiscible liquids.

Thus, an immiscible liquid can be defined as two liquids that are completely insoluble in each other. Such a system actually consists of two phases. One other example is benzene and water. An important result is that the boiling point of an immiscible mixture must be lower than the boiling point of either of its components.

A example of polar covalent compound is water. This reduces electrostatic forces of attraction that result in free ions in aqueous solution. Therefore, ionic compounds dissolve in water. Petroleum is a non-polar organic solvent and can dissolve non-polar covalent compounds.

Note. It should be noted that two immiscible liquids, such as oil and water, are separated through separatory funnels. The principle is that when a mixture of two immiscible liquids is kept in a separatory funnel, the liquid separates in layers depending on their density, with the heavier one forming the upper layer.
