15 Questions
What is a solvent in a solution?
A substance that dissolves the solute
What determines the rate of dissolution of a solute in a solvent?
The frequency of collision between solute and solvent molecules
In a solution, what happens to the dissolved solute in relation to the solvent's physical state?
It follows the physical state of the solvent

Why does granulated sugar dissolve faster than a sugar cube?
Granulated sugar has a larger surface area.
How does an increase in temperature affect the dissolution rate of solutes?
Increased temperature weakens intermolecular forces between solute molecules.
