Can anything change a solution?
Adding more solute or more solvent can change a solution.
What could you do to change an unsaturated solution to a saturated solution?
Keep adding solute until the solvent cannot disslove any more at that given temperature.
How do you precipitate soluble complex?
Add salt to the solution. Change the temperature of the solution. Let the solvent evaporate in increase the concentration of the soluble complex. Change the pH of the solution.
Suppose you have a solution of two perfectly miscible liquids Liquid A is the solvent and liquid B is the solute How can you change the solution so that liquid B becomes the solvent?
you switch the names of the liquids a=b b=a
Is the preparation of sugar solution physical change?
Yes. Both the sugar and the water (or other solvent) remain the same chemicals. Since no chemical change occurs during creation of the solution, it is a physical change.
Why you need to heat the solution in order to prepare supersaturated solution?
Effect of heat would be the solvent will be dissolved fast and the temperature changes contribute to the change of the effect of the supersaturated solution.
Can anything change a solution?
Adding more solute or more solvent can change a solution.
What can change solutions?
Adding more solute or more solvent can change a solution.
What happens if a solvent is added to a solution?
I presume from category that the question ask about the heat of dissolution. Assume the solvent and solution is at thermal equilibrium. Adding more solvent would yield change in interaction for non ideal solution and thus it could yield increase or decrease of temperature depend on the infinite heat of solution of the solute that we interested in. Adding more solvent would not yield temperature change for ideal solution.

Is a solution a physical or chemical change?
A solution is not a change; a solution is represented by a solute dissolved in a solvent; but dissolving (without chemical reaction) is a physical process.
When a solution is heated and a gas is formed is that a chemical change?
If there is no chemical reaction occurring in the solution as a result of heating then this scenario constitutes a phase change.

What physical change happens to atoms and molecules in a solution that is strongly heated in a flame?
The solvent is vaporized.
What are two ways you can change the concetration of a solution?
Adding more solute or adding more solvent
