How can we separate naphthalene from sand?
Naphtalene is soluble in toluene, for example.
With the help of an experiment how will you separate a naphthalene ball and a mixture of naphthalene and sodium chloride?
it is done by forming a derivative of naphthalene. Eg. adding picric acid (in methanol) to the mixture forming naphthalene picrate. the mixture of biphenyl and naphthalene picrate can be easily separated by filtering. residue: naphthalene picrate. filtrate: biphenyl. derivative is transformed back to original substance.
Naphthalene is a sublimate. A sublimate is a substance which changes directly from the solid state to the gaseous state and vice-versa. So, by utilising this property, we can separate the mixture of sodium chloride and naphthalene by heating it. The naphthalene will sublimate and we'll be left with sodium chloride.
Write for equations for the reactions used to separate and recover m-nitroaniline benzioc acid and naphthalene?
to separate the mixture of sand and sugar:- first: you can mix water in it and after mixing you can separate the water and sand. and after that you boil the water until whole water is evaporated and you get sugar and sand separated. second: if difference b/w size of sugar and sand particle you can use met to separate them.
