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