What is the definition of solvation?
Solvation is the combination of a solvent with the molecules of the solute.
What causes the partial positive and negative charges of water?
What causes the partial positive and negative charges of water?
The unequal sharing of electrons between the hydrogen and oxygen atoms creates partial positive and negative charges.

Study Notes
Solvation with Water
- Solvation is the process where a solvent combines with the molecules or ions of a solute
- Water's polarity is key to its solvation properties
- Water has a partial negative charge at the oxygen pole and a partial positive charge at the hydrogen pole
- Positive ions are attracted to the oxygen pole, and negative ions are attracted to the hydrogen pole
- These attractions form hydration shells around ions and charged molecules, preventing clumping and precipitation
Water Movement in Solutions
- Molecules in a liquid can move and change their position, but intermolecular attractions prevent them from separating
- In a solution, the attraction between water molecules and the solute restricts water movement
- Water moves between solutions, but the movement is present in both directions, always
