Measuring the electrical resistivty of water we can evaluate the purity.
distillation of water
distilation
The only way is to buy a water test kit, but no water is totally pure.
pure water is made up of molecules and atomsi know this and i am in 7th grade
Ice is solid H2O so it is a pure substance, at least ideally.
Pure water is pure because it is pure... and because it is pure, it is pure... Got it... What sought of question is that?
The electrical conductivity is measured.
---- yes, i do, if you evaporate the water you leve behind the salt. this is a simple yet effective way of the separation.
Sugar and salt affect the evaporation of water differently. Sugar increases the boiling point of water, slowing down evaporation. On the other hand, salt decreases the vapor pressure of water, also slowing down evaporation. Both substances can hinder the rate of evaporation compared to pure water.
Pure water contains a very small amount of ions due to the self-ionization of water molecules where a small percentage of water molecules dissociate into hydrogen (H+) and hydroxide (OH-) ions. This process creates a small concentration of ions in pure water.
Pure water is neutral
