Nitrous acid (molecular weight = 47.01 grams) is added to pure water and the following reaction occurs: HNO2 + H* + NO2 If the initial nitrous acid concentration is 100 mg/L and the equilibrium constant K, = 4.0 x 10“, what are the equilibrium concentrations of nitrous (NO2) and nitric acid (HNO2) in mol/L? Be sure to check that your assumptions for developing an ICE table are valid. Note: Make sure you don't confuse nitrous acid for nitric acid!
