Flashcards
Solution
Solution
A homogeneous mixture of two or more substances where the different substances cannot be mechanically separated or seen. It has two parts: solute (what is dissolved) and solvent (what the solute is dissolved into).
Solubility
Solubility
The ability of a substance to dissolve in a particular solvent. Ionic compounds (aq) are often soluble and molecular compounds can be soluble depending on their polarity.
Electrolyte
Electrolyte
A substance that conducts electricity when dissolved in water. This is due to the presence of ions that can carry an electrical charge.
Non-electrolyte
Non-electrolyte
