What are a few examples of pure and impure substances around us?
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
Which methods is used to obtain pure copper sulphate from impure sample and how?
One method to obtain pure copper sulfate from an impure sample is by recrystallization. In this process, the impure sample is dissolved in water, and then the solution is heated and slowly cooled to allow pure copper sulfate crystals to form. These crystals are then filtered out and dried to obtain the pure compound.
What temperature you need to separate pure water from impure water?
Pure water can be separated from impure water through a process known as distillation. The temperature needed for this separation is 100 degrees Celsius, which is the boiling point of water. Impurities will remain behind while the pure water vaporizes and can be collected and condensed back into liquid form.
Why is the melting point of impure water lower than the melting point of pure water plus how can this be explained?
the melting point of IMPURE water is lower because excess chemicals and sediments (and whatever else making it impure) get in the way of the water freezing directly by making it so that when the the water froze, it also had to freeze the sediments and chemicals (or else it wouldn't be frozen)
How can you separate pure copper sulphate from an impure sample?
You can separate pure copper sulfate from an impure sample by dissolving the sample in water to create a solution. Pure copper sulfate will remain dissolved, while impurities will either remain undissolved or form a precipitate. You can then filter the solution to separate the impurities from the pure copper sulfate solution, which can be recovered by evaporating the water.
what the between pure and impure water?
Pure water does not contain colour but impure water contains Other compounds.
What is the difference between clean water and 100 percent pure water?
Pure water is a non-conductive substance that is toxic to life, and corrosive of most metals. Impure water is water that has impurities, such as salts, hardness, metal ions, and so on.
How is a impure water content changes to pure?
Boil it
Is water a mixture or impure substance?
yes water is mixture of many impure substances and bacteria.even pure water has some bacterias.
Is pure and impure a chemical?
Any chemical may be pure or impure.
Is rock pure or impure?
pure
How do you use impure in a sentence?
A refinery will pay less for impure gold than pure gold.
Is pencil point pure or impure?

What is prefix for pure?
impure
How can you separate the water and salt?
Salt and water can be separated by heating the salt solution. The solution is heated till the water turns into steam. When entire water steams out, the white particles left behind is known as salt. This is the first step in obtaining salt from sea water. There water is collected in large areas and the water is allowed to evaporate. After the water evaporates the salt left behind is impure. So further processes are done on that impure salt to make it pure.
