QUESTION
Polar
Answer:
Ifl al moleculel hasl Hl bonded,l andl lacksl symmetry
Canl dissolvel inl H20
QUESTION
Nonpolar
Answer:
Composedl ofl onel element,l moleculesl thatl onlyl containl al Cl andl H,l symmetryl ofl
moleculesl
Cannotl dissolvel inl H20
QUESTION
Strongl electrolytes
Answer:
Dissociatel 100%l inl water,l producingl positivel andl negativel ionsl
Forml solutionsl thatl conductl anl electricl currentl stringl enoughl tol lightl al bulbl
Breaksl downl completely
,QUESTION
Weakl electrolyte
Answer:
Dissociatesl onlyl slightlyl inl waterl
Formsl al solutionl withl al fewl ionsl andl mostlyl froml undissociatedl moleculesl
Hasl anl equilibriuml arrowl
Onlyl hasl al partiall breakdown
QUESTION
Nonelectrolytes
Answer:
Dissolvel asl moleculesl inl waterl
Dol notl producel ionsl inl waterl
Dol notl conductl anl electricl currentl
Nothingl happens
QUESTION
Solubility
Answer:
Thel maximuml amountl ofl solutel thatl dissolvesl inl al specificl amountl ofl solventl
Temperaturel sensitivel forl solutes
Typicallyl expressedl asl gramsl ofl solutel inl 100l gramsl ofl solvent,l usuallyl waterl
gl solute/l 100l gl water
QUESTION
Unsaturatedl solutions
, Answer:
Containl lessl thanl thel maximuml amountl ofl solutel
Canl dissolvel morel solutel
Hasl thel potentiall tol dissolvel solute
QUESTION
Saturatedl solutions
Answer:
Containl thel maximuml amountl ofl solutel thatl canl dissolvel
Havel undissolvedl solutel atl thel bottoml ofl thel containerl
Containl solutel thatl dissolvesl asl welll asl solutel thatl recrystallizesl inl anl equilibriuml
process
Solutel goesl tol thel bottoml
Nol morel H20l moleculesl thatl canl dissolve
QUESTION
Solubility
Answer:
Dependsl onl templ
Ofl mostl solidsl (orl liquids)l increasesl asl templ increasesl
Ofl gasesl decreasesl asl templ increases
QUESTION
