In summary, word processing software is used to manipulate text and apply basic formatting to a document. Word processing is often combined with other software in an office suite. A typical office suite includes word processing, spreadsheet, presentation and database software.
Amperometry: Measures the current produced by the titration reaction as a result of the oxidation or reduction of the analyte. The endpoint is detected as a change in the current. This method is most useful when the excess titrant can be reduced, as in the titration of halides with Ag+.
Figure 1 Setup for a Typical Titration In a typical titration, the titrant in the buret is added to the solution in the Erlenmeyer flask until the indicator changes color to show that the reaction is complete. An indicator is added to the solution being titrated. The indicator is a substance that changes color when the reaction is complete.
