Document Summary

Solution: a homogeneous mixture of two substances interacting together. Pure substance: smallest separable units compose this; chemically joined in specific proportion. Mixture: more than one smallest unit in it. Solute: the minor component of a solution; less of it. Dilute solution: a solution that contains a small amount of solute relative to the solvent. Concentrated solution: a solution that contains a large amount of solute relative to the solvent. Stock solution: a concentrated solution that will be diluted to some lower concentration for actual use; used to save preparation time, conserve materials, reduce storage space, and improve the accuracy with which working lower concentration solutions are prepared. Electrolyte: substances that dissolve in water to form solutions that conduct electricity. Weak acid: acids that do not completely ionize in water. Weak electrolyte: conduct electricity only weakly; result from weak electrolytes/acids. Insoluble: if a compound does not dissolve in water.
