At 300. K and 1.20 atm, assume that 30. mL of NO gas reacts with 25 mL of oxygen gas and excess water to produce gaseous nitric acid according to the following equation:
2NO(g) + 32O2 (g)+ H2O(l)?? 2 HNO3(g).
If all of the nitric acid produced by this reaction is collected and then dissolved into 50. mL of water, what would be the pH of the resulting solution? (Hint: before you begin, think about which reactant is the limiting reagent.)
