ionic bonding Flashcards
giant ionic structure is arranged in
positive and negative arrangement
does ionic compound has a high or low bp, mp. why
high due to strong electrostatic forces of attraction held in fixed position between positive and negative (oppositely) charged ions in lattice structure
how to overcome the electrostatic forces of attraction in lattice structure
high amount of energy and change an ionic compound from solid to liquid
lattice of ionic compound is usually soluble in _______ but insoluble in _______________
water； organic solvents (compounds containing hydrogen, carbon and oxygen; eg, ethanol, acetone, hexane, benzene)
why do water molecules dissolve ionic compounds
water molecules can separate positive ions from negative ions, causing ionic compounds to dissolve
partial ionic charge is enough to
attract oppositive charges, as long as there is a charge
water molecule is ionic or covalent
covalent compound
ionic compound conduct electricity in
aqueous state (dissolve) or in molten (melt) but not in solid state
why cant ionic compounds conduct electricity in solid state
ionic compound in solid state does not have free mobile ions (held in fixed position) to act as charge carriers to conduct electricity
ionic compounds in molten or aqueous state has
free mobile ions to act as charge carriers to conduct electricity ( can slide past one another and move from atom to atom)
why are ionic compounds not used for making perfumes
Ionic compounds are not volatile enough
Due to needing large amount of energy to overcome
Oppositely charged ions are together by strong
electrostatic forces to change liquid state to gaseous state in the giant ionic
Structure, thus having high boiling point
