Boil it. The water will evaporate, leaving salt at the bottom of the pot, which did not evaporate and was left behind.
Boil it until the water is gone. You will have a deposit of salts left behind.
Sea water has a lower freezing point than pure water due to the presence of salts, which lower the freezing point of the water. This means that sea water will freeze at a lower temperature than pure water.
I would imagine that the sea water would have to run through a water purifier.
Yes, sea water has a higher density than pure water due to the presence of dissolved salts and minerals. The higher density of sea water allows objects to float more easily in it compared to pure water.
distillation
It is a mixture. A pure substance contains only one type of substance or one species of any substance or element. Sea water is a mixture of different salts dissolved in water. Thus, it is not a pure substance. Another point is that the different components of sea water can be observed separately.
c. Sea water because it is a combination of salt and water.
Absolutely not. A pure substance is a substance that consists of only one species. This is a hypothetical scenario, as the closest thing in a household is probably copper wire. Even distilled water (a great deal purer than sea water) is a mixture of H2O and some ions.
Salt water is a homogeneous mixture called a solution containing salt and water. Salt is the solute and water is the solvent. It is a mixture because the salt and water are not chemically combined and are not present in definite proportions.
Boil it until the water is gone. You will have a deposit of salts left behind.
Yes and no. Drinking water is absolutely pure H2O. In some locales, however, the water has been augmented by the addition of chemicals. Even de-salinated sea water -- which is again pure H2O, may contain the odd natural contaminant, making it less than 'absolutely pure'.
pure substance all elements and compounds like gold, hydrogen, water, methane etc. impure substance mixtures of different substances like milk, soil, sea water, minerals etc
Yes, a coin does sink slightly faster in pure water than it does in sea water. The dissolved salts in sea water make the water denser, and as a result, objects immersed in sea water will experience greater buoyancy than they do in fresh water.
the sea water contains more salt. the pure water do not contain salt. the density of sea water is more than density of pure water. as there is more salt in sea water it is corrosive against the metals like aluminium. the pure water is not corrosive in nature. sea water is harmful for drinking. pure water is good for drinking.
No.
