The ionization constant for formic acid and acetic acid is 17.7 × 10-5 and 1.77 × 10-5. Which acid is stronger and how many times the other if equimolar concentrations of the two are taken?
Ka for HCOOH > Ka for CH3COOH. Hence formic acid is stronger. Further Strength of HCOOH Strength of CH3COOH=KHCOOHKCH3COOH−−−−−−−√ = 10−−√ = 3.16 times.
