by crystallisation, we can get pure copper sulphate crystals
What is the percentage of Morphine in pure Opium?

Is vinegar metal a pure substance or a mixture?
Vinegar is not a metal. It is a mixture of water and acetic acid.
What is vinegar appearance?

Which is more soluble in pure water at room temperature Lead Nitrate or Lead Sulphate?
All nitrates including Lead nitrate is soluble in water but Lead sulphate is almost insoluble.
How can you separate pure copper sulphate from an impure sample?
Dissolve in water and crystallize once more. The resulting crystals will be purer, while the remaining solution will comprise of the dopants + copper sulphate
What is The name of the copper sulphate after being heated?
Copper Sulphate usually is found in a hydrated form (i.e., water molecules are incorporated into the crystals.) Pure copper sulphate is a pale, greenish gray color. The familiar blue color only occurs in hydrates of copper sulphate (i.e., in crystals that incorporate H20 molecules). Heating the blue crystals can drive off the water. It's still called copper sulphate after you do that. For substances like copper sulphate that naturally attract water, the adjective, anhydrous often is used to describe the pure (water free) state. If you heat copper sulphate to a temperature of 650C, it will decompose into something else. http://en.wikipedia.org/wiki/Copper_sulphate
Is it impossible for an element to replace atoms of anothe element in a compound?
No. In a displacement reaction, that is exactly what happens. If an element low down in the reactivity series is in a compound, and you add an element that is higher placed in the reactivity series. The more reactive element will displace the less reactive element in the compound.Example:Copper Sulphate - Copper is low in the reactivity series and is in a compoundSodium + Copper Sulphate - Sodium is higher in the reactivity series than copper, and is in it's pure elemental form.Copper + Sodium Sulphate - The Sodium that is higher in the reactivity series has switched places with the Copper, which is lower in the reactivity series.FULL EQUATION:Sodium + Copper Sulphate --> Copper + Sodium Sulphate
Is cider a homogenous mixture?
Cider vinegar is a homogeneous mixture. This is because it contains a small percentage of water. Pure vinegar is a compound.
