front 8 Chemical Indicator | back 8 any substance that gives a visible sign, usually a color change, when exposed to an acid or a base |
front 9 Dissociation | back 9 a process in which compounds split into smaller particles such as atoms, ions, or radicals, usually in a reversible manner |
front 10 Electrolyte | back 10 a compound that conducts an electric current when it is in an aqueous solution or in the molten state |
front 11 Equivalence Point | back 11 point at which there are equal quantities of hydronium ions and hydroxide ions. |
front 12 Hydronium ion | back 12 [H.O*] the positive ion that is formed when a water molecule gains an hydrogen ion |
front 13 indicator | back 13 a chemical compound added in small amounts to a solution so the pH (acidity or basicity) of the solution can be determined visually. |
front 14 lonization | back 14 a process by which a neutral compound becomes electrically charged by gaining or losing electrons in an aqueous solution |
