WebMay 27, 2016 · Yes, equations must be balanced, thus the only correct way to write this is: N X 2 H X 4 + H X 2 O ↽ − − ⇀ N X 2 H X 5 X + + O H X − Easy to remember: Nitrogen typically has a free electron pair which can act as a Lewis base for a proton. If your textbook says 4, it is an error in your book. Good job on spotting it and realising it. Share
WebMar 5, 2008 · What is the pH of a 0.20 M solution of hydrazinium chloride, N2H5Cl? Hydrazine, N2H4, is a weak base with Kb = 1.7 x 10-6. N2H5+ + H2O ßà N2H4 + H3O+ Ka = Kw/Kb = 1.0 x 10-14 / 1.7 x 10-6 = 5.9 x 10-7 Ka = [H+] [ N2H4] / [ N2H5+] Using an ICE table and assuming that x is very small will yield the relationship: Ka [ N2H5+] = x2 WebThe pH of ~0.002 mol of H3O+ ions = 1.698 (rough rounding, but lower pH value...) Is it correct to say then that because the incremental H3O+ mols are so negligent, we overlook …
WebFeb 3, 2013 · H2NNH2 (aq) + H2O (l)--> For the reaction of hydrazine (N2H4) in water, Kb is 3.0 10-6. H2NNH2 (aq) + H2O (l)--> H2NNH3+ (aq) + OH- (aq) Calculate the concentrations of all species and the pH of a 1.6 M solution of hydrazine in water. [OH-] = [H2NNH3+] = [H2NNH2] = [H+] = pH = asked by Daniel February 3, 2013 1 answer WebSo, now that we're adding the conjugate base to make sure we have roughly equal amounts, our pH is no longer 2. It might be somewhere like a 5. So now we have a strong buffer with a lot of capacity, but our pH of this buffer solution is very different from the pH of just the weak acid/conjugate base we started with. Comment ( 4 votes) Upvote
