Chapter 13: Water, the Universal Solvent Flashcards
What is a solution?
A homogenous mixture in which molecules or ions are evenly dispersed throughout a solvent
What is a solution?
A homogenous mixture in which molecules or ions are evenly dispersed throughout a solvent
What are aqueous solutions?
Solutions in which water is the solvent
When does a solution form?
When the bonds between the solute and solvent particles are sufficiently strong to compete with attractive forces between the solute and solvent particles
What does the ‘like dissolves like’ rule predict?
Polar solutes will dissolve in polar solvents and non-polar solutes will dissolve in non-polar solvents
What makes water so essential to life?
Its solvent properties, as it provides transport of nutrients in living organisms and provide an aqueous environment for chemical reactions
What do soluble ionic compounds do in water?
They dissociate in water to form hydrated ions
What is the attraction of a hydrated ion?
Water molecules are attracted to the central ion by ion-dipole attractions
When does a precipitation reaction occur?
When two solutions of compounds are mixed and a solid product is formed, known as a precipitate
What are spectator ions?
Ions that are not directly involved in the formation of the precipitate during a precipitation reaction
Which type of equation does not include spectator ions?
Ionic equations
What are aqueous solutions?
Solutions in which water is the solvent
When does a solution form?
When the bonds between the solute and solvent particles are sufficiently strong to compete with attractive forces between the solute and solvent particles
