Problem
A particulate representation of an aqueous glucose solution depicts each solute particle as “C₆H₁₂O₆⁺” and “C₆H₁₂O₆⁻,” with oriented water molecules forming hydration shells around the two species. Which statement best explains why this diagram is inaccurate?
(a) Water molecules should orient their hydrogen atoms toward the glucose molecules rather than their oxygen atoms.
(b) Glucose molecules do not dissociate into ions in water and should be shown as intact neutral molecules dispersed among the solvent.
(c) To portray a concentrated solution, the diagram should contain twice as many glucose particles for the same number of water molecules.
(d) The diagram should include separate Na+ and Cl− ions because glucose solutions always contain background electrolytes.
