Could somebody explain the phrase like dissolves like?

Answer 1

This means that substances are more likely to dissolve in other substances with similar chemical properties. It is most often used when discussing polar and nonpolar solvents. For example, oil will not dissolve in water because oil is nonpolar and water is polar. Basically, a polar solvent will generally dissolve polar solutes and sometimes ionic solutes, and a nonpolar solvent will generally dissolve nonpolar solutes.

Answer 2

"like dissolves like" means that polar solvents dissolve polar solutes, and that on-polar solvents dissolve non-polar solutes.

for example: water (a polar solvent) dissolves salt NaCl (polar solute, forms Na+ Cl-)

Answer 3

"Like dissolves like" is a principle in chemistry that refers to the tendency of substances with similar polarities to mix or dissolve in each other. For example, polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes. This principle helps predict solubility and interactions between different substances.
