Is formic (HCOOH) an acid or base? Weak or Strong

WebA conjugate acid-base pair is a pair of substances that differ by one H+ ion. For example, HCl and Cl− are a conjugate pair where HCl is the acid and Cl− is the base. Similarly, NH3 and NH4+ are a conjugate pair where NH4+ is the acid and NH3 is the base. Note that the acid in each pair has more H atoms and the higher charge. C6H5NH3+ WebHCOOH (aq) = 0.200 7.
