Question | Answer |
Hydride | A compound of hydrogen and at least one other element of lower electronegativity. |
Hydrocarbon | A compound of hydrogen and carbon. |
Hydrogen, Aromatic | A hydrocarbon which has alternating single and double covalent bonds in six-membered carbon rings. |
Hydrogen Bond | A weak chemical bond between a hydrogen atom in one polar molecule and the electronegative atom in a second polar molecule of the same substance. |
Hydrogenation | The addition of hydrogen to a material. |
Hydrolysis | An acid-base reaction between water and an ion of a dissolved salt. |
Hydrolysis, Anion | Reaction in which a negatively charged ion base accepts a proton from a water molecule, increasing the OH- ion concentration of the solution. |
Hydrolysis, Cation | Reaction in which a positively charged ion acid donates a proton to a water molecule, increasing the H^3O^+ ion concentration of the solution. |
Hydronium Ion | A hydrated proton of the H^3O^+ ion. |
Hydrosol | A suspensoid in which water is the dispersing medium. |
Hydrous Oxide | A hydrated metal oxide. |
Hygroscopic | Absorbing and retaining moisture from the atmosphere. |
Hypothesis | A possible or tentative explanation. |
Ice Point | 0 degrees Celsius. |
Immiscible | Not capable of being mixed. |
Indicator | A substance which changes in color on the passage from acidity to alkalinity, or the reverse. |
Inertia | Resistance of matter to change in position or motion. |
Ingot | A molded block of metal. |
Inhibitor | A substance which hinders catalytic action. |
Inorganic | Pertaining to material which are not hydrocarbons or their derivatives. |
Insoluble | Not capable of being dissolved. |
Internal Phase | The dispersed particles of a colloidal suspension. |
Ion | An atom or group of atoms with an unbalanced electrostatic charge. |
Ion-Exchange Resin | A reaction which can exchange hydronium ions for positive ions; and exchange hydroxide ions for negative ions. |
Ion, Spectator | An ion in a reaction system which takes no part in the chemical action. |
