chapter 4: Chemical Reactions in Solution Flashcards
for a reaction to occur, species must
collide
solvent: component that has the same … as the …
physical state; solution
solute: substance being … to form a solution; typically in … than the solvent; often a … but can also be a … or …
dissolved; lesser amounts; solid; gas; liquid
solution: a … mixture; often composed of substances …
homogeneous; dissolved in water
most common solvent:
water
solutions with water as solvent:
aqueous solutions
most ionic compounds:
electrolytes
strong electrolytes separate
Completely into ions
;solutions of strong electrolytes are good
conductors of electricity
compounds that dissolve but do not conduct electricity are …. they do not dissociate into ions when …
nonelectrolytes; dissolved
molecular compounds that only partially .. in solution are called …
ionize; weak electrolytes
acetic acid is a
weak electrolyte
double arrow indicates that the reaction proceeds in
both directions
acids that ionize completely are known as
strong acids
strong and weak acids are also
strong and weak electrolytes
weak electrolytes produce only a … when dissolved in water
few ions
solubility: the concentration of solute that exists in … with an … of that substance
equilibrium; excess
(soluble ionic compounds) no exceptions:
group 1 cations and ammonium; nitrates; perchlorates; acetates
(soluble ionic compounds) exceptions:
chlorides, bromides, iodides (except Ag, dimercury, lead (II))
sulfates (except, dimercury, lead (II), Sr2+, barium)
(insoluble ionic compounds) with exceptions of only group 1 cations and ammonium
carbonates; phosphates
(insoluble ionic compounds) with exceptions group 1 cations, ammonium, and others
hydroxides (except group 1, ammonium, Sr2+, barium)
solubility must be determined
experimentally
a precipitation reaction involves the formation of an …. from the reaction of …
insoluble product(s); soluble reactants
the products, if any, of many reactions of ionic compounds can be predicted from
solubility rules
