A Solution is formed when two or more substances combine to yield a mixture that is homogeneous at the molecular level. Is a container filled with water (H,O) and some beach sand (SiO2) a solution? O Yes, because SIO, dissolves completely in water to form Si(aq) and O (aq) solvated ions. O No, because water is not capable of forming homogeneous solutions. O No, because SiO, is a nonpolar covalent molecule that does not dissolve completely in water to form solvated ions. O Yes, because water reacts violently with beach sand to form H2SIO3, Metasilicic Acid, a diprotic strong acid.
