What is the name of the part of a solution doing the dissolving?

• Solvent

• Solute

• Supersaturated

• Insoluble

Mixtures that are the same throughout are called

• heterogeneous solutions

• homogeneous solutions

• insoluble solutions

• elements

• elements and solutions

• elements and mixtures

• elements and compounds

• Mixtures and solutions
