Are the
liquids/ solutions
safe to drink
?
Liquids/ Solutions
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)
Fractional Distillation
Simple distillation
Evaporation
Once the make-up is known. Use pre-existing research to define whether 'safe to drink'
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
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
Combustion ability
Density
Boiling point/ freezing point
Testing by senses
Taste
Touch
Look
Scent
Mixing/ attempting to create a reaction with other mixtures
Examine solution under microscope
Safe to drink
How to define 'safe to drink'?
By whom?
Humans
'Healthy' humans
'At risk' humans (with a pre-existing medical problem)
Animals
Aquatic life (when in waterways)
In what quantity?
Consuming the undiluted solution
When in a small quantity in a beverage
Eg. As a containment
When adverse effects begin from consumption of something unsafe?
Short term effects/ instantaneous dangers
Causing problems in bodily systems
Eg. respiratory/ digestive problems
Causes potential for damage in some humans
Eg. may re-ignite past problems/ make existing conditions worse
Long-term effects/ dangers of consumption
Causes unnatural cell growth
Eg. Cancer
Effects DNA reproduction
Eg. Genetic problems/ mutations
How often?
Unsafe when collective build-up is high?
Consumption everyday for prolonged period
Difficult to test under time constraints.
Safe if consumed once?
Twice?
Once a year?
Difficult to test under time constraints
