The dissociation constant of formic acid and acetic acid are 2.14×10^-4 and 1.81×10^-5 respectively. What is the relative strength of the acids

The formic acid is 3.5 times stronger than acetic acid.

Explanation:

The strength of an acid depends on its acid dissociation constant.

For a hypothetical monoprotic acid HA, the dissociation equilibrium is:

More is the value of , greater is the dissociation and stronger is the acid.

Thus formic acid is 3.5 times stronger than acetic acid.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
