10.) how can we change the solubility of a substance?\n11.) what is a saturated solution?\n12.) what is an…

Brief Explanations:

10. Solubility can be changed by altering temperature (for most solids in liquids, solubility increases with temperature; for gases in liquids, it decreases with temperature), pressure (affects gas - liquid solubility significantly), and by adding other substances that may react or complex with the solute.
11. A saturated solution is one in which the maximum amount of solute has been dissolved in a given amount of solvent at a specific temperature and pressure, and any additional solute will not dissolve.
12. An unsaturated solution contains less solute than the maximum amount that can be dissolved in the solvent at a particular temperature and pressure.
13. A supersaturated solution has more solute dissolved than the maximum amount that would be dissolved under normal conditions at a given temperature and pressure. It is unstable and the excess solute may crystallize out.
14. Electrolytes are substances that conduct electricity when dissolved in water or melted, because they dissociate into ions.
15. A strong electrolyte dissociates completely into ions in solution, while a weak electrolyte only partially dissociates.
16. Nonelectrolytes are substances that do not conduct electricity when dissolved in water or melted as they do not dissociate into ions.

Answer:

10. By changing temperature, pressure, or adding other substances.
11. A solution with maximum dissolved solute at a given T and P.
12. A solution with less than maximum dissolved solute at a given T and P.
13. A solution with more than maximum dissolved solute (unstable).
14. Substances that conduct electricity when dissolved or melted due to ion dissociation.
15. Strong electrolytes dissociate completely, weak ones partially.
16. Substances that do not conduct electricity as they do not dissociate into ions.
