Chemistry
type of solution • 2 types↑ pure substances => Homogeneous Mixture
Solution = solute + solvent *H₂O is always solvent
conductivity of BSolution
•
electrolyte solution: solute can dissociatio→ion => conduct (v)
• non-eletrolyte solution: solute can't dissociationtion => conduct (x)
types of solution
,
• aqueous solution: H₂O is the solvent express by ['laq
non-
-aqueous
solution: C₂H5OH - CCl4 are the solvent (organic solvents)
