we use 1 g of unknown acid added with 120 mL of distilled water ,the solution filtered , then we took 25 mL of this unknown acid for titration.
we use NaOH base for titration ,the volum of titrated base when it reach the equivalence point was 3.2 mL . and the concentration of NaOH is 0.1 M.
calculate the numbers of moles of NaOH = 0.0003233 mol
Q: What is the initial concentration of unknown acid ?
The PH of acid 3.43
What is the Ka of the weak acid
