Nitric acid (HNO3), a strong acid, is formed in the following reaction.
2 NO(g) + 3/2 O2(g) + H2O(g) â 2 HNO3(g).
Assume a volume of 22.4 mL of NO gas (at STP = 1 atm, 273 K) completely reacts with
excess of oxygen and water. If all of the acid that is formed is dissolved into 50. mL of
water, what should be the pH of the solution? (pH = - log[H+])?
A) 1.0
B) 1.7
C) 2.0
D) 3.0
E) 2.3
