C6H12O6 is the chemical formula for glucose, a simple sugar. Glucose is a neutral molecule, meaning it doesn't donate or accept protons (H+ ions) in solution.

Therefore, an aqueous solution of glucose will have a pH close to 7, which is neutral.

Note: While glucose itself is neutral, the pH of a glucose solution can be slightly affected by the presence of impurities or by the interaction of glucose with water molecules. However, these effects are generally negligible and the pH will still be close to neutral.
