The solvent dissolves the
Solute
What is the component of a solution which remains the same after mixing
Solvent
Solvation / Dissolution happens when
Attractive forces between solute and solvent are stronger than those between particles
The solubility of a solute is measured as the
Maximum amount of solute that can be dissolved in a particular solvent at a particular temperature
The solubility of a substance depends on
The temperature of the solution, solvent, and pressure
The solubility of liquids and solids increases with
Increasing temperature
The solubility of a gas increases with
Decreasing temperature and increasing pressure
What is a solution in which solute:solvent is small
Diluted
What is a solution in which solute:solvent is large
Concentrated
The mole fraction of a compound is the
Number of moles of compound / number of moles of all components
Molarity is the
Number of moles / Liters of solution
Molality is the
Number of moles / Kg of solvent
