If a 1.00 mL sample of the reaction mixture for the equilibrium constant experiment required 32.40 mL of 0.258 M NaOH to titrate it, what is the acetic acid concentration in the mixture?
We know the formula
M1V1=M2V2
Given M2=0.258
V2=32.40 ml
V1= 1 ml
Calculate M1=?
Puting value in formula
M1×1 ml = 0.258 molar×32.40 ml
M1 = 8.3592 molar of acetic acid

The equilibrium constant for the reaction shown here is K. = 9.0 x 102. A reaction mixture at equilibrium contains [A] = 4.3 x 10-3 M. A (9)=B (9)
The purpose of the lab was to find the equilibrium constant of
the rxn of acetic acid and ethanol to yield ethyl acetate and
water. Hydrochloric acid is used as a catalyst. We have to
determine the equilibrium concentrations of all the species (water
included) present at equilibrium. In test tubes, different
concentrations of the equilibrium system were prepared then
titrated with NaOH to determine the total acid content of the
system at equilibrium. From this you will be able...
