Interpretation: To describe what happens when a sugar cube completely dissolves in a glass of water.
Concept Introduction: When two substances of the same type are mixed, they form a true solution.
Answer to Problem 1STP
Correct answer: When a sugar cube completely dissolves in a glass of water, a solution is formed.
Explanation of Solution
Reason for correct option: A true solution is formed when a sugar cube is completely dissolved in water. The so-formed solution has a uniform composition; thus, it is called a homogenous solution. In this solution, one behaves as a solute which is the sugar cube while water behaves as a solvent.
Reasons for incorrect options: The solution of sugar in water cannot be a colloid as a colloid is a heterogenous solution. An emulsion is a colloidal dispersion where a liquid dissolves in a liquid. The particle’s size in a suspension is much larger than the solution that the particles settle down in the bottom.
