I have a solvent which dissolves a solute 0.8 gr in each liter.(assume)
If I reduce the solvent concentration to half, what changes will be accrue?
in fact, I want to know what is relation between solvent concentration and its capacity to dissolve a specific solute?
Additional information :
dilutant is water
solute is copper oxide nanoparticle
my original solvent is: ammonium chloride solution NH4Cl ( 1 molar)
First of all, your "solvent" is properly a solution. In fact you want to dissolve NH4Cl and CuO in water. Thus you have a ternary system (with almost unlimited solubility of NH4Cl in water and possible interactions between the solutes) the chance that your CuO solubility will be exactly inverse linear with NH4Cl concentration is small. With the iteration programs available nowadays you could get a pretty good idea about it from about 5 carefully selected different solutions as Darren suggested above.
If maximum 0.8 g dissolve in in 1 Liter, then 0.4g dissolve in the half (500mL)
No! I don't want to reduce solvent volume. i want to reduce solvent concentration.
Can you send more information, what is your solvent and what is its concentration? Normally solvents like water, alcohol, DMSO,.. has no concentration!
my original solvent is : ammonium chloride solution NH4Cl ( 1 molar)
I do not know which compound you want to dissolve!
You may try to dissolve max amount (saturated solution) and after filtration then analyze the amount dissolved from your compound by UV for example.
I would think it would depend on the polarity of the solute and the polarity of the dilutant.
Is the dilutant water? If so, how soluble is the solute in water alone?
If availability of NH4Cl is an issue, find out the polarity of your solute and try diluting with something which it is soluble in.
Otherwise - Why not try it and find out? Try a range of concentrations, plot a graph and you could probably publish that in itself!
is there any other way to find out the relation except doing experiment?(i have no plenty of time and money :( )
is it right to state that there is a linear relation between solvent concentration and its capacity to dissolve a specific solute?

it depend on your solutes and solvent. interactions between them may change every thing! you have to know properties of solvent and solute and then you can use thermodynamic models. if you find data for interaction between them you are a lucky man!
GOOD LUCK
