Are the liquids/ solutions safe to drink?
Liquids/ Solutions
Safe to drink
How to define 'safe to drink'?
By whom?
In what quantity?
Humans
Animals
Aquatic life (when in waterways)
Consuming the undiluted solution
When in a small quantity in a beverage
When adverse effects begin from consumption of something unsafe?
Short term effects/ instantaneous dangers
'Healthy' humans
'At risk' humans (with a pre-existing medical problem)
Whether or not 'safe to drink' is defined by what is in the solutions
Discover what components are in the solutions
Separation techniques (of liquids)
Once the make-up is known. Use pre-existing research to define whether 'safe to drink'
Fractional Distillation
Simple distillation
Evaporation
Considering the potential volatility of solutions with what is encountered when consumed
Eg. Mixing liquids with human stomach acid to see if a dangerous reaction occurs
Long-term effects/ dangers of consumption
Causes unnatural cell growth
Causing problems in bodily systems
Causes potential for damage in some humans
Effects DNA reproduction
Eg. Cancer
Eg. Genetic problems/ mutations
Eg. may re-ignite past problems/ make existing conditions worse
Eg. As a containment
How often?
Unsafe when collective build-up is high?
Consumption everyday for prolonged period
Safe if consumed once?
Twice?
Once a year?
Difficult to test under time constraints
Difficult to test under time constraints.
Ways of testing the solution?
Attempting to find the solution (rather than all its ingredient
Then, use pre-existing research to determine whether it's safe
Examine properties and see if they are similar to researched solutions
Examine solution under microscope
Combustion ability
Density
Boiling point/ freezing point
Testing by senses
Mixing/ attempting to create a reaction with other mixtures
