The equilibrium constant ( K_a ) for the dissociation of nitrous acid (HNO₂) can be expressed as:
[ K_a = \frac{[H^+][NO_2^-]}{[HNO_2]} ]
This equation represents the equilibrium concentrations of the products (hydrogen ions and nitrite ions) divided by the concentration of the undissociated nitrous acid. The value of ( K_a ) for HNO₂ is approximately ( 4.5 \times 10^{-4} ) at room temperature, indicating it is a weak acid.
