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.
Is pure salt a compound?
no . its not a pure compound because Salt is Pure Of Impure.............
Who has higher melting point Pure or Impure Substance?
A pure substance typically has a higher melting point than an impure substance. Impurities disrupt the regular arrangement of particles in the substance, making it more difficult for them to overcome the intermolecular forces and transition from solid to liquid state. This results in a lower melting point for impure substances.
What is the difference between pure and impure?
the different between pure and impure is: 1.pure:means one kind of one thing for example:pure oxygen means only the element oxygen but in the air we have lots of elments beside the air like hydrogen ,nitrogen...etc 2.impure:the opposite from the pure :P
Are a mixture pure or impure?
impure because they are made of more than 1 substance
If the compound is impure what can be done to verify the purity of a compound in chromatography?
match it to a known pure standard
What is meant by a substance and a pure substance?
A substance might be pure with a single compound or impure with impurities along with principal compounds.
How are a compound and a pure substance different?

Are compounds impure?
Yes, compounds can be impure if they contain other substances or impurities alongside the desired compound. Impurities can affect the compound's properties and purity level. Purification methods, such as filtration or distillation, can help remove impurities from compounds.
Is rock pure or impure?
pure
Is tap water in a glass a compound homogeneous or heterogeneous?
Pure water (H2O) is a chemical compound; if the water is impure may be a homogeneous or heterogeneous mixture.
How is the melting of an impure compound expected to change with recrystallization?
During recrystallization, impurities are removed as the compound is dissolved and then slowly cooled to allow for the formation of pure crystals. As a result, the melting point of the compound should increase after recrystallization because the presence of impurities lowers the melting point of the compound.
Is HCl a pure compound?
Well that is somewhat loaded it is pure in and of itself, it can be impure but it can be pure. Adding other gasses to it (its a gas at room temp when not dissolved in water to make the acid) would make it impure. Adding things to the acid which do not react could also be seen as impurities. Bear in mind there is no way to make the actual molecule impure by say making HOCl because this is no longer HCl but a different compound (hypochloric acid)
Is pencil point pure or impure?
Pure
Is pure salt a compound?
