Question

Formic acid, which is a component of insect venom, has a k a = 1.8 × 10 –4. what is the [h3o +] in a solution that is initially 0.10 m formic acid, hcooh

Answer 1

Formic acid is a weak acid. The equilibrium representing the acid dissociation of formic acid is,

`HCOOH (aq) + H_(2)O(l)<==> HCOO^(-)(aq) + H_(3)O^(+)(aq)`
