Reactions in aqueous solutions Flashcards
Dissociation
The splitting of ionic compounds into its ions
Dissolution
The process where ionic crystals break up into ions in water
Ionisation
The reaction of a molecular substance with water to produce ions
Hydration
The process where ions become surrounded with water molecules
Cations
Positively charged ions (e.g. Na^+, Mg^2+, Al^3+, NH4^+,
etc.
Anions
Negatively charged ions (e.g. Cl^-, S^2-, O^2-, NO3^-, SO4^2-, etc.
Electrolyte
A substance that contains free ions and behaves as an electrically conductive medium
Precipitate
The solid that forms in a solution during a chemical reaction
Ion exchange reaction
A type of reaction where the positive ions exchange their respective negative ions due to a driving force
