The equilibrium constant for the dissociation of acetic acid at 25oc is 1.85x10-5. what will be the equilibrium concentration of h+ at 25oc, if the initial concentration of acetic acid was 0.100 m? ch3cooh (aq) ↔ ch3coo- (aq) + h+ (aq) give your answer to two significant figures and in decimal form.

Equilibrium concentration of is

Explanation:

Construct an ICE table to calculate changes in concentration at equilibrium.

I:     0.1                                                          0                     0

C:     -x                                                          +x                   +x

E:    0.1-x                                                       x                      x

=

(species inside third bracket represent equilibrium concentrations)

or,

So, M

or,

So, equilibrium concentration of ==x=

the answers would be

the first one and the second one

a corroding iron, if that's one of your choices
