"You learned about mixtures, especially solutions and the factors that affect their makeup and properties. Why is it important to know the properties of both solutes and solvents when preparing a solution that is expected to meet a certain need? Does this involve a chemical change or a physical change? Explain."

Can u pls help me

its due to the solvents being factored. to be prepared for the solution you would need a chemical change as the solvents get factored so this will mean that it will have a chemical reaction. in this case its slightly different so it will be called a chemical change as 2 different chemicals change and evolve.

Explanation:

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

there are two significant figures.
