Water and its Solvent Properties

What makes water a universal solvent?

• High acidity

• Lack of hydrogen bonds

• Low boiling point

• Polarity and ability to form hydrogen bonds

How does water's polarity contribute to its ability to dissolve many substances?

• Water's polarity causes it to form covalent bonds with other substances

• Water's polarity has no effect on its ability to dissolve substances

• Water's polarity allows it to repel other substances

• Water's polarity allows it to form hydrogen bonds with other polar or ionic substances

What is the role of hydrogen bonding in water's solvent properties?

• Hydrogen bonding only allows water to dissolve gases.

• Hydrogen bonding prevents water from dissolving any substances.

• Hydrogen bonding allows water to dissolve many different substances.

• Hydrogen bonding has no effect on water's ability to dissolve substances.

Give an example of a substance that can easily dissolve in water and explain why.

• Salt

• Sand - because it is also a mineral

• Sugar - because it is sweet

• Oil - because it is a liquid

Explain the concept of solvation and how it relates to water as a solvent.

• Water is a poor solvent because it cannot form any bonds with solute particles

• Water is a good solvent because of its ability to form hydrogen bonds with solute particles, allowing for effective solvation.

• Solvation has no relation to water as a solvent

• Water is a solvent because it repels solute particles

What factors can affect the solubility of a substance in water?

• Time of day

• Distance from the equator

• Temperature, pressure, and the nature of the solute and solvent

• Color of the container

How does the temperature of water affect its ability to dissolve solutes?

• Higher temperatures generally increase the solubility of most solids, liquids, and gases.

• Higher temperatures decrease the solubility of most solids, liquids, and gases.

• The temperature of water has no effect on its ability to dissolve solutes.

• Lower temperatures generally increase the solubility of most solids, liquids, and gases.

Discuss the importance of water as a solvent in biological systems.

• Water causes harm to biological systems as a solvent

• Biological systems do not require water as a solvent

• Water is important as a solvent in biological systems because it allows for chemical reactions and transport of nutrients.

• Water is not important as a solvent in biological systems

What are some common everyday examples of water acting as a solvent?

• Sand dissolving in water

• Metal dissolving in water

• Salt dissolving in water, sugar dissolving in water, and coffee or tea brewing are common everyday examples of water acting as a solvent.

• Oil dissolving in water

Explain the term 'like dissolves like' and how it applies to water as a solvent.

• Water dissolves substances based on their color.

• Water dissolves nonpolar substances because it is a nonpolar solvent.

• Water dissolves substances based on their weight.

• Water dissolves polar substances because it is a polar solvent.
