A | B |
Acids | ions or compounds that produce hydrogen ions when dissolved in water. Acidic compounds have a pH less than 7 |
Alkaline | any solution that has a pH value greater that 7 |
Bases | ions or compounds that that produce OH- (hydroxide) ions when dissolved in water |
Heavy Metal Ions | ions of heavy metals (lead, mercury, cadmium), which have high atomic weights and tend to be harmful to living matter |
pH | an expression of the acidic or basic character of a solution. A neutral (balanced) solution = 7 |
Unsaturated Solution | a solution that contains less dissolved solute than the amount that the solvent can normally hold at that temperature |
Saturated | the point at which the solvent will not dissolve any more of a solute |
Solute | the dissolved species in a solution |
Solubility | the quantity of a given substance that will dissolve in a given quantity of solvent to form a saturated solution at a particular temperature |
Solubility Curve | a graph indicating the solubility of a particular solute at different temperatures |
Supersaturated | a solution containing a higher concentration of solute than a saturated solution at a specified temperature |
