Student Set – Titration and analytical chemistry – Digital Set – 14 Experiments

ABOUT THIS PRODUCT:

Function and Applications

Equipment set for conducting student experiments on the topics of titration and anion detection. This device set can be used to perform 21 attempts on the following topics

• Effect of acids and bases
• Acid-base titrations
• Determination of the pH value of an acid
• Cation detection by flame dyeing
• Anion detection by flame dyeing
• Titration curves
• Henderson-Hasselbalch equation
• Buffer systems

Benefits

• 7 Tests can also be carried out digitally, in addition, 6 of these offer a didactic added value compared to the classical variant
• In addition to the classic tests, SMARTsense can be used for 2 further tests
• THE ideal combination of classical experiments (competence to act) and digital measurement (media literacy)
• Future-proof: Prepare for the transition to the digital school today
• Perfectly matched to digital science lessons with tablets (iOS and Android) and smartphones (Android)
• Faster & higher learning success: The use of digital devices increases identification and thus increases the motivation of the students
• Experimental literature available for students and teachers: Minimum preparation time
• Tailored to education plans: All thematic areas covered
• Set developed by educators to introduce analytical chemistry

Equipment and technical data

• The device set consists of all the components necessary for the tests; only a burner that is suitable to the existing gas supply must be purchased separately
