Are these liquids or solutions safe to drink?
Identifying the solution
Density
Determine the mass of a 10mL sample
Melting Point
Ice bath method, watching signs of crystallisation
Boiling point
Hot water bath method, watching signs of boiling and evaporation
Solubility
Two samples of identical solution, checking for solubility with ethanol
Drinking water test
pH level of solution
How to measure pH level
Digital pH meter
pH universal test strips
Measures the acidity
Most aquatic organisms are only able to survive within a pH range of 6 to 8
Chloride test
Levels of chloride identifies the minerals dissolving and potential industrial pollution
Pesticides
reverse osmosis
Classify 'safe to drink'
What makes the solution not safe to drink?
Pathogenic Micro Organisms
Waterbourne diseases
Is the solution purely water?
Determine if the solution was safe to drink
Observe the tested individual for a time period after the experiment was conducted
Identity the differences to the tester's health and body after consuming the solution
Test on a large audience in the event of an outlier or potential immunity problems
