K_{eq} is the?
The formula:
3H_{2} + N_{2}⇌2NH_{3}_{
}It is written?
 equilibrium constant

The equilibrium constant shows
 the if there is more reactant than product at equilibrium.
 the extent to which the forward and reverse reaction take place.

How is Ionization constant symbolized?
K_{w}, K_{a}, etc.

Set up the solution for this problem:
At 25oC, a 0.100 M solution of HC_{2}H_{3}O_{2}
is 1.34% ionized and has an [H+]
of 1.34 x 10^{3} mol/L. Calculate Ka for acetic acid.
HC_{2}H_{3}O_{2}⇌H+C_{2}H_{3}O_{2}
 HC2H3O2=.1.00134=0.099mol/L reactant
 HC2H3O2 yields 1 mole of both, so equal moles of each=1.34 x 103 mol/L, HC2H3O2
 =1.8X10^5

Ionic Equilibria problems measure...
the pH from the ionization constant K_{a}

what's the solubility product constant
K_{sp}

5 steps for writing the Sparingly soluble solids
 K_{sp}:
 1) ionize the salt
 2) write the Ksp expression
 3) determine the moles of the ions
 4) substitute into the Ksp expression
 5) Ksp has no denominator

The solubility of AgCl in water is 1.3 x 10^5 mol/L.
AgCl(s)⇌Ag+(aq) + Cl(aq)
Set up this solution
[Ag]=[Cl]=is 1.3 x 10^5, so
(1.3 x 10^5 )(1.3 x 10^5 )=1.7X10^10

Write the Ksp expression for PbSO4
Then, substitute x.
 PbSO4⇌Pb^2+SO4^2
 Expression Ksp=[Pb^{+2}][SO_{4}^{2}]
 Substitute x: Ksp=[X][X]

What is hydrolysis?
term used for general reactions which a water molecule is split

how do you buffer a solution?
what do I need to know about them?
 a weak acid mixes with it's conjugate base form a buffer solution
 they resist pH changes with small dilutions

the oxidation number represents
# of e lost, gained, & unequally shared.
Lost/gained=metal & nonmetal. (ionic bond)
unequally shared=2 mor more nonmetals. (covalent)

what does a positive & negative oxidation # mean?
 +=fewer electrons
 =more electrons

All elements in their free state (Na, Cu, Mg, H2, O2, Cl2, N2) have an oxidization number of
zero.

H is +1, except in ______, where it is___ (eg NaH, CaH)
metal hydrides, 1

O s 2, except in ____, where it is ___, and OF_{2}, where it is ___
peroxides, 1, +2.

The metallic elements in ionic compounds has a ____ oxidation number
positive

In covalent compounds, the ____ oxidation number is assigned to the most ____
negative, electronegative

The algebraic sum of the oxidation numbers of the elements in a compound is
0

The algebraic sum of the oxidation number of the elements in a polyatomic ion is ____ the charge of the ion
equal to

Determine the oxidation number for manganese on potassium permanganate (polyatomic ion)?
KMnO4
 K=+1(1)=1
 O=2(4)=8
 1+8+X=0, so Mn=7
