Identify the substance which can dissolve in water:

Correct answer: All of the above

Explanation: Glucose, urea, and acetone all dissolve in water, so the correct answer is “All of the above.” 📚 Other Information: ▪️ Glucose is soluble due to multiple –OH groups forming hydrogen bonds. ▪️ Urea dissolves easily in water, forming hydrogen bonds. ▪️ Acetone is polar and mixes with water completely. ▪️ Water is known as the "universal solvent." ▪️ Solubility depends on polarity and intermolecular forces. ▪️ Ionic compounds like NaCl also dissolve in water. ▪️ Non-polar substances (like oil) are insoluble. ▪️ Solubility plays a major role in biological systems and chemistry.
