CH 13 Solutions!

CH 13 Solutions!

CH 13 Solutions!. Solution = stable homogeneous mixture; has the same composition throughout, does not settle out, and particles are dissolved; can’t distinguish phases under a microscope The solute is what gets dissolved and the solvent is what does the dissolving.
