Study Notes

Definition of Solute

A solute is a substance that is dissolved in a solution, typically in a lesser amount compared to the solvent.

Solvent-Driven Particle Interaction

A solvent pulls solute particles apart and surrounds them when the solute particles are attracted to the solvent molecules, often due to interactions like hydrogen bonding, ion-dipole attractions, or van der Waals forces.

Homogeneous Mixtures

'Homogeneous' refers to a type of mixture where the components are uniformly distributed, meaning that the composition is the same throughout. Examples include saltwater and air.

Important Parameter of a Solution

Concentration is a critical parameter, indicating the amount of solute present in a given volume of solvent, affecting the solution's properties and reactions.

Aqueous Solution Terminology

The term 'aqueous solution' denotes a solution in which water is the solvent. It is commonly used in chemistry to describe reactions and dissolutions occurring in a water medium.
