Question

Write an equilibrium reaction for a saturated solution of glucose undergoing a process of dissolving and solidifying.

a) C6H12O6 (s) ⇌ C6H12O6 (aq)
b) C6H12O6 (aq) → C6H12O6 (s)
c) C6H12O6 (s) + H2O (l) ⇌ C6H12O6 (aq)
d) C6H12O6 (aq) + H2O (l) → C6H12O6 (s)

Answer 1

The equilibrium reaction for a saturated solution of glucose undergoing a process of dissolving and solidifying is represented by the equation C₆H₁₂O₆ (aq) + H₂O (l) → C₆H₁₂O₆ (s).

Step-by-step explanation:

The correct answer is d) C₆H₁₂O₆ (aq) + H₂O (l) → C₆H₁₂O₆ (s).

In this reaction, a saturated solution of glucose (C₆H₁₂O₆) dissolves in water (H2O) to form an aqueous solution (C₆H₁₂O₆ (aq)). As the solution cools or evaporates, the glucose molecules come together and solidify to form a solid (C₆H₁₂O₆ (s)).

This process of dissolving and solidifying represents a dynamic equilibrium between the dissolved and solid forms of glucose. The equation can be used to depict the reaction:

C₆H₁₂O₆ (aq) + H₂O (l) → C₆H₁₂O₆ (s)
