What are you doing when you dilute a solution?
What is solute?
What is solvent?
What is concentration?

Since we change the volume by diluting a solution (adding water, adding volume) that can't be it. Concentration also changes because concentration depends on volume of solution, and if we add volume, we change the concentration. And it can't be the amount of solvent, because by definition, diluting a solution is adding solvent. so it the amount of solute remaining
I think diluting means when you separate solutions. A solute is the minor component, and solvent is able to dissolve.
i agree with @rushwr you increase the volume you decrease the concentration of solute
Thank you all for the explanations :)
If we have a solution, we have a certain amount of a solute (e.g. a solid) mixed together with a certain amount of a solvent (i.e. a liquid). We may have a saturated solution (i.e. not enough solvent to dissolve the solute at room temperature, for example) or a dilute solution (i.e. where we have excess solvent required to bring all our solid solute into solution at room temperature).
Diluting a solution involves decreasing its concentration/strength (i.e. the number of moles of the solute per litre of solution) by adding more solution. In doing so, we must naturally increase the solution's original volume. We do not add any more solute in this process, as a dilution can only involve the weakening of the solution's concentration, not any increase.
I wouldn't necessarily agree with you @superhelp101 in saying that dilution is about
"separating solutions", maybe you're thinking about something called 'serial dilution', where often you take a certain volume of a solution of a known concentration, add it to a new container and then make it up to the mark with solvent to create a weaker solution of the same substance, whose concentration we can calculate. Anyway, this isn't required to answer the question you posed. Hope that helps! :)
