Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A solute that contains polar molecules will dissolve in a solvent that contains
A
nonpolar molecules
B
polar molecules
C
covalent molecules
D
equal-sized molecules
Explanation: 

Detailed explanation-1: -The rule of thumb is that “like dissolves like". Polar/ionic solvents dissolve polar/ionic solutes and non-polar solvents dissolve non-polar solutes. For example, water is a polar solvent and it will dissolve salts and other polar molecules, but not non-polar molecules like oil.

Detailed explanation-2: -That is, solutes typically will dissolve best in solvents that have the most molecular similarities: polar solutes will dissolve better in polar solvents, and nonpolar solutes will dissolve better in nonpolar solvents.
