| Frage | Antworten |
| Solution | A homogeneous mixture (uniform, 1 phase) of 2 or more substances |
| Concentration | The ratio of quantity of solute to solvent; usually quantity of solute per unit volume of solution |
| Concentrated Solution | Solution with a relatively large quantity of solute dissolved per unit volume of solution |
| Diluted Solution | Solution with a small quantity of solute dissolves per unit volume of solution |
| Alloy | Solution of two or more metals |
| Aqueous Solution | Solution in which water is the solvent. All are transparent, can be colored or colorless |
| Hydration | Ions surrounded by H2O molecules -> stabilize ions |
| Dissociation | Separation of ions that occurs when an ionic compound dissolves |
| Miscible | Able to mix to form a solution; usually describing liquids that mix with each other in all proportions to form a solution |
| Immiscible | Unabke to mix to form a solution; usually describing liquids that do not readily mix |
| LDF | Weakest intermolecular force and no attraction between water molecules |
| Surfactants | Compound that can reduce the surface tension of a solvent; surfactants have both a hydrophobic part and a hydrophilic part |
| Solubility | Quantity of solute that can dissolve in a given quantity of solvent |
| Saturated solution | Solution that contains the maximum quantity of solute at a given temperature and pressure |
| Unsaturated Solution | Solution in which more solute can dissolve at a given temperature and pressure |
| Super Saturated Solution | Solution that contains more than the maximum quantity of solute it should at a given temperature and pressure |
| Amount Concentration | The amount (in moles) of solute dissolved per litre of solution; unit symbol is mol/L |
| Stock Solution | Concentrated solution that is used to prepare dilute solutions for actual use |
| Concentration formula | C = n ÷ V |
| Standard Solution | Solution for which the precise concentratiom is known |
| Dilution | Process of reducing the concentrations of a solution; usually done by adding more solvent |
| Dilution equation | C1V1 = C2V2 |
| Percentage Volume ÷ Volume (%V/V) | Cv/v = (V solute ÷ V solution) × 100% |
| Percentage Weight ÷ Volume (%W/V) | Cw/v = (m solute ÷ V solution) × 100% |
| Percentage Weight ÷ Weight (%W/W) | Cw/w = (m solute ÷ m solution) × 100% |
| Parts per million (ppm 1: 10^6) | Cppm = (m solute ÷ m solution) × 10^6 ppm |
| Parts per billion (ppb 1:10^9) | Cppb = (m solute ÷ m solution) × 10^9 ppm |
| Parts per trillion (ppt 1:10^12) | Cppt = (m solute ÷ m solution) × 10^12 ppm |
