is the amount of that substance that can be disolved in a given quantity of solvent
any substance with a solubility less than 0.01 mol/L
which ions inperticular are soluble in water
all common ionic compounds or the alkali metal ions (group 1A) and of the ammonium ion (NH4+)
what must you do to predict whether a precipitate forms when we mix aqueous solutions of two strong electrolytes?
1)note the ions present in the reactants
2) consider the possible combinations of the cations and anions
3)use table 4.1 to judge solubility
complete ionic equation
an equation written with all soluble strong electrolytes shown as ions
Spectator ions
ions that appear in identical forms among both the reactants and products of a complete ionic equation
what role do they play in the reaction
they are present but play no direct role in the reaction
net ionic equation
are what is left after all spectator ions have been ommitted from the equation
what does a net ionic equation include
it only includes the ions and molecules directly involved in the reaction
what is the first step for writing a net ionic equation
write a balanced molecular equation for the reaction
what is the second step for writing a net ionic equation
rewrite the equation to show the ions that form in solution when each soluble stong electrolyte dissociates or ionizes into is component ions. only strong electrolytes dissolved in aqueous solution are written in ionic form
Acids and bases are...
common electrolytes
are substances that ionize inaqueous solutions to form hydrogen ions, thereby increasing the concentration of H+ ions.
why is H+ simply a proton
beacuse a hydrogen atom consists of a proton and an electron
Acids are often called what
proton donors
Bases are
substances that accept H+ ions.
What do bases produce and when
they produce hydrogen ions when they dissolve in water
Can compounds that do not contain OH- ions be bases
yes they are
What happens to ammonia when it is added to water
it accepts an H+ ion from the water molecule and thereby produces an OH- ion
Strong acids and bases are
acids and bases that are stron electrolytes (completely ionized in solution)
when are strong acids more reactive than weak acids
when the reactivity depends only on the concentration of H-
is a weak base
what is a neutralization reaction
when a solution of an acid and that of a base are mixed
what characteristic properties does the product of the reaction have
the products of the reaction have none of the characteristic properties of either the acidic or the basic solutions
what does the term salt mean
any ionic compound whose cation comes from a base
what reaction produces water and salt
a neutraliztion reaction between an acid and a metal hydroxide
what happens in precipitation reaction
cations and anions come together to form an insoluble ionic compound
what is corrosion
the conversion of a metal into a metal compound by a reaction between the metal and some substance in its environment
what happens when a metal corrodes
it loses electrons and forms cations
loss of electrons by a substance is called what
