Students take advantage of the natural ability of red cabbage juice to perform as a pH indicator to test the pH of seven common household liquids. Then they evaluate the accuracy of the red cabbage indicator, by testing the pH of the liquids using an engineer-designed tool, pH indicator strips. Like environmental engineers working on water remediation or water treatment projects, understanding the chemical properties (including pH) of contaminants is important for safeguarding the health of environmental water sources and systems.
Investigate what makes something soluble by exploring the effects of intermolecular attractions …
Investigate what makes something soluble by exploring the effects of intermolecular attractions and what properties are necessary in a solution to overcome them. Interactive models simulate the process of dissolution, allowing you to experiment with how external factors, such as heat, can affect a substance's solubility.

You are employees of competing Water Testing companies. You recently received a request from the municipality of Cavour to test their water for an unknown/suspected parasite that they suspect has been causing nausea and intestinal distress in their community.
Your mission after developing the Method for testing for the parasite found in the City of Cavour’s water is to submit your report for approval by the City of Cavour.
Your report and presentation will be used to determine whether Cavour accepts your bid for the contract.
