| Question | Answer |
|---|---|
| Two water molecules produce a hydronium ion and a hyroxide ion by transfer of a proton. | self-ionization |
| A solution is defined as the negative of the common logarithm of the hydrogonion ion concentration. | pH |
| the negative of the common logarthim of the hydroxide ion concentration. | pOH |
| compounds whose colors are sensitive to pH | acid-base indicators |
| the pH range over which an indicators change color | transition interval |
| determines the pH of a solution by measuring the voltage betweeen the two electrodes that are placed in the solution | pH meter |
| 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 unknow concentration | titration |
| the point at which two solutions used in a titration are present in chemically equivalent amounts | equivalence point |
| the point in a tritation at which an indicator changes colors | end point |
| the solution that contains the precisely known concentration of a solute | standard solution |
| a highly purified solid compound used to check the concentration of the known solution in a tritation | primary standard |
