| Question | Answer |
|---|---|
| Self-ionization of water | two water molecules produce a hydronium ion and a hydroxide ion by the transfer of a proton |
| pOH | the negative of the common logarithm of the hydroxide ion concentration |
| pH | a solution is defined as the negative of the common logarithm of the hydronium ion concentration |
| Acid -base indicators | compounds whose colors are sensitive to pH |
| transition interval | the pH range over which an indicator changes color |
| pH meter | determines the pH of a solution by measuring the voltage between the two electrodes that are placed in the solution |
| Titration | the controlled addition and measurement of the amount of a solution of known concentration required to react completely with a measured amount of a solution of unknown concentration |
| equivalence point | the point at which two solutions used in a titration are present in a chemically equivalent amounts |
| end point | the point in a titration at which an indicator changes color |
| standard solution | the solution that contains the precisely known concentration of a solute |
| primary standard | a highly purified solid compound used to check the concentration of the known solution in a titration |
