Question | Answer |
combination of substances that can be separated by physical means and can either be the same throughout (homogeneous) or have different parts with different compositions (heterogeneous) | mixture |
homogeneous mixture made up of two or more materials where one material seems to disappear into the other; can be unsaturated, saturated, or supersaturated and can be classified as gaseous, liquid, or solid | solution |
in a solution, the substance that dissolves into another substance | solute |
in a solution, the substance that dissolves the solute | solvent |
solution in which water is the solvent | aqueous |
maximum amount of a solute that can be dissolved in a given amount of solvent; can be affected by temperature and pressure | solubility |
solution that contains the total amount of solute that it can hold under specific conditions | saturated |
measure of the amount of solute in a solution compared to the amount of solvent | concentration |
solution that contains a large amount of solute per given amount of solvent | concentrated |
solution that contains a small amount of solute per given amount of solvent | dilute |
substances that contain hydrogen and produce positively charged hydronium ions when they dissolve in water, forming acidic solutions | acid |
substances that produce negatively charged hydroxide ions when they dissolve in water, forming basic solutions | base |
measure of how acidic or basic a solution is, related to its concentration of hydronium ions and hydroxide ions; solutions with a pH below 7 are acidic; solutions with a pH above 7 are basic; solutions with a pH of 7 are neutral | pH |
compound that reacts with acidic and basic solutions and changes color at different pH values | indicator |
the interaction between acids and bases in which the properties of each are canceled out by the other and a neutral solution is produced | neutralization |
