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

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

Answer: (B)

Verified step by step guidance

1. Understand the concept of a 'universal solvent': A universal solvent is a substance that can dissolve a wide range of solutes. Water is often referred to as the universal solvent due to its ability to dissolve many different substances.
2. Identify the properties of water: Water has several unique properties, including high specific heat capacity, high surface tension, polarity, and the ability to dissolve polar substances.
3. Focus on 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 water to interact with and dissolve other polar substances.
4. Consider the options given: Evaluate each option in the context of water's properties. Low specific heat capacity and non-polarity do not apply to water, while high surface tension is a property but not directly related to its solvent capabilities.
5. Conclude with the correct property: The ability to dissolve polar substances is the property of water that contributes to its role as the universal solvent, due to its polar nature allowing it to interact with and dissolve other polar molecules.
