What is the percent dissociation for acetic acid in vinegar
Vinegar is a 5.0% solution by weight of acetic acid (ch3co2h)in water. Given that the ph for acetic acid is 2.41, the ka=1.8X10-5 and assuming the density of vinegar to be 1.00g/cm3, what is the percent dissociation for acetic acid in vinegar?
