Question

Formic acid, hcooh, is a weak acid present in the venom of red-ants. at equilibrium, [hcooh] = 2.00 m, [hcoo− ] = 4.0 × 10− 1 m, and [h3o+ ] = 9.0 × 10− 4 m. __________________

a. write the equilibrium expression for the ionization

Answer 1

See below

Step-by-step explanation:

`\rm HCOOH + H_(2)O \rightleftharpoons H_(3)O^(+) + HCOO^(-)`

The general formula for an equilibrium constant expression is

`K_(eq) = \frac{[\text{Products}]}{[\text{Reactants}]}`

For this reaction,

`K_(eq) = \frac{[\text{HCOO}^(-)][\text{H}_(3)\text{O}^(+)]}{[\text{HCOOH}]}`
