Advanced Chemistry System

Code: 7610.01

The perfect complement for the General Chemistry System

The Advanced Chemistry System was designed to enhance the potential of the General Chemistry System.

Used alongside the General Chemistry System, the Advanced Chemistry system allows users to perform all the experiments described in the Manuals and discover even more chemical reactions and laboratory analysis techniques. In only a few minutes students or teachers can set up several different organic, inorganic and analytic chemistry experiments.
The experiments included in the Instruction Manual allow users to perform over 90 experiments in association with the equipment in the General Chemistry System.

EXAMPLE OF USE: Plotting a Titration Curve

This experiment allows students to study the progression of a titration of a strong acid with a strong base. Titration is a technique used to discover the concentration of a solution. In a titration, the test substance (the analyte) reacts with a reagent added as a solution of known concentration. The volume of titrant required to completely react with the analyte is measured. The end point of a titration can be detected instrumentally using a pH meter, in the case of an acid-base titration, or by exploiting the electric properties of the solutions. A chemical indicator, which changes colour in basic or acidic environments, is usually added to the analyte to indicate the turning point. It is possible to observe the progression of a titration, such as the neutralization of a strong acid with a strong base, by recording the pH values as titrant is added and then plotting these values on a graph. The curve is shown by joining the points drawn on the graph. This experiment also introduces students to computer analysis of data.
