The solution is absorbed onto a piece of paper
it is mixture
An element is an element and can not, in anyway, be separated.
Yes, it is possible.
A solution can be separated in two ways. 1) Evaporation 2) Distilation
A solution can be separated by evaporating the water which will leave the solutes on its own and the solvent as a gas.
Yes, copper sulphate(CuSO4) can be separated from its solution in crystalline form.
Filtration
by leaching the solution with nitric acid
Brass is a solution as it is homogenous in composition. In cannot be separated out. The particles are as one and do not hang where there could be spun out. Since they cannot be separated, brass is a solution.
The solution is absorbed onto a piece of paper
yes
No, it is not true.A solution can be separated by reverse osmosis; you need a semi-permeable membrane and a means to apply pressure.
A Compound is a chemically combined entity. It cannot be separated physically. A Solution is a physically combined entity. Hence, it can be separated physically.
The mixture of sugar-salt solution can be separated by evaporation. If the water is completely evaporated we will get separated sugar from the mixture. If we dissolve the mixture in alcohol we will get the salt separated while sugar will be dissolved in alcohol. After that, the solution is further filtered and salt will be the residue of the solution.
a solution
mixture because the solution can be separated by evaporating the water.
