Students have asked these similar questions
1. Seawater is composed of salt, sand, and water. Is seawater a heterogenous mixture or homogenous mixture?
2. Suppose there are four unknowns in bottles: three of the bottles are solutions and one is a pure substance. How are you going to determine which of the unknown is a pure substance?
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.
Which of the following is a pure substance that can be broken down into simpler substances by chemical means?
Solution
Compound
Heterogeneous mixture
