Question | Answer |
---|---|
Two water molecules produce a hydronium ion and a hydroxide ion by transfer of a proton | Self-ionization of water |
The negative of the common logarithm of of the hydronium ion concentration | pH |
The negative of the common logarithm of the hydroxide ion concentration | pOH |
Compounds whose colors are sensitive to pH | Acid-base indicators |
The pH range over which an indicator change 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 |
The controlled addition and measurement of the amount of a solution of unknown concentration | Titration |
The point at which the two solutions used in a titration are present in chemically equivalent amount | equivalence point |
The point in a titration at which an indicator changes color | end point |
The solution that contains the precisely known concentration of a solute | Standard solution |
Highly purified solid compound used to check the concentration of the known solution in a titration | Primary solution |
