Making Sense of Solubility Kit
Product Code : EL-AS-11124
Last updated: 6 October 2026
Quick answer: An inquiry kit in which students generate their own solubility data for ionic compounds, then use supplied graphs of solubility against pH, temperature and pressure to explain how cave speleothems form.
The structure of this kit is what makes it worth noting: students build a general model of solubility from data they collect themselves by reacting aqueous solutions of ionic compounds, rather than being given the rule and asked to confirm it. The stated learning objective is to analyse student-generated empirical data in order to develop and test an evidence model.
The anchoring phenomenon is cave formation. Students combine their hands-on results with provided graphs of solubility against pH, against temperature and against pressure to work out the mechanism behind the dissolution of calcium carbonate that leads to speleothem growth. A final investigation guides them through the effect of pH on calcium carbonate solubility specifically. Tying an abstract solubility rule to stalactites gives the topic somewhere to land.
The listing does not state the number of students or groups the kit supports, the reagents and quantities supplied, the grade level, or whether consumables can be replenished. Those are the figures you need in order to order against a class size, so request them before purchase. Ask also for the safety data sheets for the ionic compounds supplied.
Note: this item is filed under Atomic Structure in the catalogue, although its subject is the solubility of ionic compounds rather than atomic structure. The category has been left as the catalogue has it.
