1. The problem statement, all variables and given/known data what is the pH of a 4.5x10-8M solution of nitric oxide? 3. The attempt at a solution well first off.. NO(aq) + H2O(l) <-------> HNO+(aq) + OH-(aq) or???........................-->HNO2(aq) + H+(aq) Now I have no idea how much of the nitric oxide is actually going to react with the water. I could probably find a Ka value for this reaction online but that would be cheating there must be a way to figure this out without doing that.
