Problem- A 20.00 mL sample of propanoic acid, HC3H5O2, is titrated with strong base. The end point is reached upon addition of 30.00 mL of base. The following data is obtained
mL of base : 9 mL pH 2.64, mL base: 10 mL pH = 4.59 , mL base: 15 pH= 4.89 ,
mL base: 25 pH = 5.59, mL base: 30 pH ? mL base 35 pH = 12.38
Find Ka using above data
What is molarity of acid
What is molarity of base
What is pH of solution at equivalence point?
mL of base
I am need of complete solution for this problem please help- me out to get right solution
