Calculation of NO2 Formation



  • NO2 is formed from NO by oxidation.

  • The molar mass of NO is 30 g/mol.

  • 600 ppm of NO means 600 mg of NO per L of air.

  • So, the number of moles of NO in 100 L of air is:


    • (600 mg/L x 100 L) / 30 g/mol = 2000/3 moles


  • NO is completely oxidized to NO2, so the number of moles of NO2 formed is also 2000/3 moles.

  • The molar mass of NO2 is 46 g/mol.

  • So, the mass of NO2 formed is:


    • (2000/3 moles) x 46 g/mol = 30666.67 mg = 30.67 g




Calculation of NO2 Dissolved in Water



  • NO2 is dissolved in 10 L of water.

  • The density of water is 1 g/mL.

  • So, the mass of water in 10 L is:


    • 10 L x 1000 mL/L x 1 g/mL = 10000 g


  • The concentration of NO2 in the water is:


    • (30.67 g) / (10000 g) = 0.003067 g/g = 3.067 mg/g




Calculation of pH of the Solution



  • NO2 reacts with water to form nitrous acid (HNO2):


    • NO2 + H2O → HNO2 + H+


  • The dissociation constant (Ka) of HNO2 is 4.5 x 10^-4.

  • So, the equilibrium expression is:


    • Ka = [H+][NO2-] / [HNO2]


  • Assuming that all of the NO2 dissolves in water:


    • [NO2-] = 3.067 mg/L / 46.0055 g/mol x (6.022 x 10^23 molecules/mol) / 1000 mg/g / 10 L = 1.05 x 10^-7 M


  • Let x be the concentration of H+ and NO2- (since they are equal due to 1:1 stoichiometry):


    • Ka = x^2 / (1.05 x 10^-7 M - x)


  • Solving for x using the quadratic formula:


    • x = 1.49 x 10^-4 M


  • The pH of the solution is:


    • pH = -log[H+] = -log(1.49 x 10^-4 M) = 3.83
