Potassium measurement with Cobra SMARTsense

Principle

Potassium measurement by means of an immersion sensor for soil analysis (evaluation of the fertiliser status in the soil), content analysis of plant parts and ion analysis in chemistry lessons.

Benefits

• Particularly comprehensible and didactically prepared description of the experiment (relevance to everyday life etc.) incl. protocol questions.

• Teach with an eye to the future: Integration into digital science lessons with tablets or smartphones.

• Increased motivation among pupils through the use of the intuitive measureAPP.

• Increased media competence.

TasksApplication of an analytical measuring method by examining the chloride content of various chloride-containing solutions

• Measurement of the potassium concentration of soil solutions and preparations of plant parts (e.g. banana fruit)

• Determination of the potassium concentration in analytical chemistry

Learning Objectives

• Examination of the potassium content of different samples in biology and chemistry lessons
