Question

experiment 4: nature of the solute - sugar dissolution observations: - salt dissolution observations: - which substance dissolved more completely?

Explanation:

Step1: Recall solubility knowledge

Solubility of sugar and salt can vary based on factors like temperature and solvent. In general conditions in water, both are highly soluble.

Step2: Consider typical solubility

Sugar (sucrose) and common - salt (sodium chloride) are both very soluble in water. But sugar often dissolves more readily and may seem to dissolve more completely in some cases due to its ability to form hydrogen bonds with water molecules more extensively in certain scenarios. However, under standard conditions, it can be difficult to distinguish a significant difference. If we assume ideal conditions and no impurities, sugar usually dissolves more completely as it has a higher solubility in water at room temperature compared to salt in many cases.

Answer:

Sugar
