| Define: Self-ionization | "Self-ionization" is a term describing the reaction in which tow water molecules react to produce ions. |
| Define: Ion | An "ion" is an atom or groups of atoms that has a positive or negative charge. |
| How does an "ion" get a positive charge? | For an ion to have a positive charge it "losses an electron". |
| How does an "ion" get a negative charge? | For an ion to have a positive charge it "gains an electron". |
| Define: Neutral Solution | A "Nuetral Solution" is aqueous solution in which the concentrations of hydrogen and hydroxide ions are equal; which means it has a pH of 7.0. (the hydrogen is positive and the hydroxide is negative-they balance each other out to become neutral) |
| What is the "Ion-product Constant" for Water (Kw) | The "Ion-product Constant" for water is the product of the concentrations of the hydrogen ions and hydroxides ions in water. |
| Define: Acid Solution | An "acid solution" is any solution in which the hydrogen-ion concentration is greater than the hydroxide-ion concentration. |
| Define: Basic Solution | An "basic solution" is any solution in which the hydroxide-ion concentration is greater than the hydrogen-ion concentration. |
| Define: Alkaline Solution | An "alkaline solution" is another name for a "basic solution". |
| Define: pH | The "pH" of a solution is a number used to denote the hydrogen-ion concentration, or acidity, of a solution; it is the negative logarithm of the hydrogen-ion concentration of a solution. |
| Define: Aqueous Solution | An "aqueous solution" is water that contains dissolved substances. |
| What is the product of hydrogen-ion concentration and hydroxide-ion concentration equal to? | For aqueous solutions, the product of hydrogen-ion concentration and hydroxide-ion concentration is equal to 1.0 x 10^-14 |
| What has a solution in which hydrogen is greater than 1 x 10^-7M? | A solution in which hydrogen is greater than 1 x 10^-7 M has a pH less than 7.0 and is acidic. |
| What is the pH of pure water or an neutral aqueous solution? | The pH of pure water or an neutral aqueous solution is 7.0. |
| What is a solution with a pH greater than 7? | A solution with a pH greater than 7 is basic and has a H+ (hydrogen) of less than 1 x 10^-7. |
| What is the symbol "H+" stand for? | The symbol "H+" stands for hydrogen-ions. |
| What is the symbol "OH-" stand for | The symbol "OH-" stand for hydroxide-ion. |
| What is an indicator? | An "indicator" is a valuable tool for measuring pH because its acid form and base form and have different colors in solution. |
