* Polarity: Sugar is a highly polar molecule due to the presence of many hydroxyl groups (-OH). Water is also a polar molecule. "Like dissolves like," meaning polar substances dissolve well in other polar substances.
* Intermolecular Forces: Sugar forms strong hydrogen bonds with water molecules, which helps it dissolve readily. Copper sulfate, while somewhat polar, forms weaker interactions with water.
* Solubility Data:
* Sugar (sucrose): About 200 grams of sugar can dissolve in 100 grams of water at room temperature.
* Copper Sulfate: Only about 20 grams of copper sulfate can dissolve in 100 grams of water at room temperature.
Therefore, sugar's high polarity, strong interactions with water, and higher solubility values make it much more soluble than copper sulfate.
