Which of the following is a property of water that contributes to its role as the universal solvent?

• A. Non-polarity
• B. Low specific heat capacity
• C. High surface tension
• D. Ability to dissolve polar substances

Answer: (D)

Verified step by step guidance

1. Understand the concept of polarity: Water is a polar molecule, meaning it has a partial positive charge on one side and a partial negative charge on the other. This polarity allows it to interact with other polar substances.
2. Recognize the significance of water's polarity: The polar nature of water molecules enables them to surround and interact with various solutes, particularly those that are also polar or ionic, facilitating their dissolution.
3. Consider the molecular interactions: When water molecules encounter polar substances, they form hydrogen bonds or electrostatic interactions, which help break apart the solute molecules and distribute them evenly throughout the solution.
4. Evaluate the options given: Non-polarity would not contribute to water's ability to dissolve polar substances, as non-polar molecules do not interact well with polar molecules. Low specific heat capacity and high surface tension are properties of water but do not directly relate to its solvent capabilities.
5. Conclude with the correct property: The ability to dissolve polar substances is directly related to water's polarity, making it an effective universal solvent.
