what does shaking do that inceases the solubility of a solution?

Shaking does not affect the solubility, but it will increase the rate that solids dissolve, and will also promote the formation of an emulsion if the ingredients are not soluble (e.g, vinegar and oil salad dressing). See if you can figure out some reaspons why. I do not see any evidence of your own thinking in the questions that you have posted.
