Document Summary
Alloys: metals that are mixed to form a solution. The most common solutions are when solids or liquids are dissolved in liquids. Solute: the substance that is being dissolved and is present in the smaller amount. Solvent: the substance that dissolves the solute and is present in greater amount. Characteristics of solutions: solutions are homogeneous mixtures, solutions are clear and do not disperse light, solutions will not settle on standing, solutions will pass through a filter. Solubility: how much of a solute will dissolve in a certain amount of solvent. Since non-polar molecules have no attractions, they simply mix together. Temperature: as temperature increases, solids become more soluble in water and gasses become less soluble in water. Pressure: pressure doesn"t affect the solubility of liquids or solids, but as pressure increases, the solubility of gas increases (at low pressure, gas escapes in bubbles)
