Question

What is the solvent in a liquid-liquid solution?

Answer 1

A solvent is a substance that dissolves a solute and forms a solution as a consequence. A liquid is the most common type of solvent, although it can also be a solid, a gas, or a supercritical fluid. Water is the most frequent solvent utilised by living organisms and a solvent for polar molecules; all ions and proteins in a cell are dissolved in water within the cell.

Complete answer:
A solution is a sort of homogenous mixture that is made up of two or more components. A solute is a material that is dissolved in another substance, known as a solvent, in such a combination. The mixing of a solution takes place at a scale where the effects of chemical polarity are present, resulting in solvation-specific interactions. When the solvent makes up the majority of the combination, as is often the case, the solution takes on the state of the solvent. The concentration of a solution, which is a measure of the quantity of solute in a given amount of solution or solvent, is an essential metric. When one of the solvents is water, the phrase "aqueous solution" is used.
Liquid solutions
Almost all gases, liquids, and solids may be dissolved in a liquid solvent. Some instances are as follows:
Gas in liquid:.
Water with oxygen
Because the solution is followed by a chemical reaction, carbon dioxide in water is a less straightforward case. The visible bubbles in carbonated water are not the dissolved gas, but rather an effervescence of carbon dioxide that has escaped solution; the dissolved gas is invisible because it is dissolved at the molecular level.
Liquid in liquid:
To create a constant, two or more compounds with the same chemistry but varying concentrations are mixed together. (Solution homogenization) Alcoholic drinks are just ethanol solutions in water.
Alcoholic drinks are just ethanol solutions in water.
Solid in liquid::
Water containing sucrose (table sugar).
Any salt in water that forms an electrolyte: sodium chloride (NaCl) (table salt) or any other salt: Salt dissociates into ions as it dissolves.
Aqueous solutions are water-based solutions that are quite prevalent.
When the liquid solvent isn't water, it's called a non-aqueous solution.

Note:
Due to liquid-liquid phase separation, an emulsion is a combination of two or more liquids that are typically immiscible (unmixable or unblendable). Emulsions are part of a larger category of two-phase matter systems known as colloids. Although the words colloid and emulsion are frequently interchanged, emulsion should be used when both the dispersed and continuous phases are liquids. One liquid (the dispersed phase) is distributed in the other in an emulsion (the continuous phase). Vinaigrettes, homogenised milk, liquid biomolecular condensates, and various metalworking cutting fluids are examples of emulsions.
