Exploring Aqueous Solutions and Solvation Processes

The video explains how solvation occurs in aqueous solutions, focusing on the differences between covalent and ionic solutes. It describes the process of dissolving sugar and salt in water, highlighting the role of water molecules in solvation and dissociation. The video also covers the concept of hydration shells and the use of state symbols to represent substances in different states.

What is the process called when water molecules dissolve solute particles?

• Hydration

• Solvation

• Precipitation

• Dissociation

What is the chemical formula of table sugar?

• C2H5OH

• C12H22O11

• CH4

• C6H12O6

What type of bonds connect the atoms in a sugar molecule?

• Metallic bonds

• Covalent bonds

• Hydrogen bonds

• Ionic bonds

What do we call the clusters of water molecules surrounding a solute particle?

• Solvent cages

• Hydration shells

• Water rings

• Solvation clusters

What is the term used when an ionic compound separates into ions in solution?

• Solvation
