Innovating Science® - Determination of Dissolved Oxygen Concentration
Manufacturer ID - IS9750
Students will learn about acids and bases through a class discussion and then test a dilute acid and dilute base with neutral litmus paper to learn how the paper indicates something is acidic or basic. Once that skill is learned they can move on to test some common items that would be found around their house to determine if they are acids or bases. Optional: Extra litmus paper is included to test more items either from home or around the school building for a greater understanding of acids and bases. The activity contains enough materials for 6 groups of students.
This kit has been designed to allow the analyst to perform a very simple titration to determine the dissolved oxygen concentration in their freshwater sample. The titration uses an easily identifiable color transition to indicate the end of the analysis. The kit contains everything an analyst would need to perform a water analysis either in the laboratory setting or out in the field. Kit contains enough materials to perform 40 tests.
