What should I know about the mixing of LIquids?
What should I know about the mixing of LIquids?
Liquids can be miscible or immiscible based on the polarity of the chemical bond.
Immiscible liquids will settle out based on density.
Immiscible liquids with lower densities will occupy the top layer of a density column.
Immiscible liquids with higher densities will occupy the bottom layer of a density column.
Assuming the liquids dissolve, mixing of liquids depends on the chemical bond polarity of the solute and the solvent.
Polar solutes and solvents dissolve in each other since the bond type is the same.
Nonpolar solutes and solvents dissolve in each other since the bond type is the same.
"Like dissolves like" can be described as when you mix solutes and solvents with opposite bond polarities (polar and nonpolar). The result is that they will not dissolve in each other.

Water is both essential and unique. Many of its particular qualities stem from the fact that it consists of two hydrogen atoms and one oxygen, therefore creating an unequal sharing of electrons. This video describes the concept of polarity and uses different real life examples as evidence of polarity.
This video describes Solubility, Solute, Solvent and Solutions with examples and diagrams.
This video is a lab demonstration that Compares the miscibility (whether two liquids mix to form one solution) of ethanol, hexane, and 1-butanol with water.
This video defines density and provides examples of a variety of objects.

Polar molecule has unequal electron charges.
Non-polar molecule has equal electron charges.
"Likes dissolve likes" is stated to be “liquids that are the same chemically can dissolve each other.”
In a solution, you have the solute and a solvent.
Solute is what is being dissolved in a solution.
Solvent does the the dissolving in the solution.
Density equals mass divided by volume.
