Are these liquids/solutions safe to drink?
Liquid/solution
Clear/colourless
Water
density of 1 gm/cm^3
pH should be less then 7, otherwise solution is very acidic
Alkanes
Pentane through hexadecane are liquids, methane/ethane/propane/butane are gases
Alkenes
Whether an alkene is a liquid is dependent on the molecular mass
Alkynes
First 3 are gases, next 8 liquids
Alchohol
Low molecular mass
Increasing mass means less soluble in water
Solids are room temperature
Copper sulphate used to test if water is present, if the copper turns blue water is present.
Water boiling point 100 degrees celcius
How to make the solution safe
Boiling
Testing pH of solution, with colour strips
ACTIVATED CARBON: Removes contaminants from the water by chemically bonding to it
Measuring density of liquid
ION EXCHANGE: Uses resin to replace harmful ions. Used to soften water
Hydrocarbon liquids
Occur as gases at atmospheric temperatures
Liquids as pressure gets much higher
When crude oil is refined into petroleum products
Hydrocarbon liquids will float on water
Much less dense then water
Very high energy density
Low thermal efficiency
Drinkable
Does the liquid have an odour?
Does the liquid become cloudy when reacting to different environmental temperatures?
Are all the liquids the same temperature?
Is salt able to be dissolved within the liquids?
