The formula for calculating the pH is as follows.. A buffer is a solution that resists changes in pH when small amounts of H+ or OH- are added. This system acts as a buffer because the ammonia reacts with acid and the ammonium ion reacts with bas

  1. PH3 has the middle boiling point because it has dipole-dipole attractions. These are weaker than hydrogen bonding but stronger than van der waals dispersion forces
  2. I should have NH4+/NH3but I have also CH3COO- that I think it gives the reaction: CH3COO- + H2O ---> CH3COOH + H3O+
  3. NH3 is not liquid but gas at STP. It is however very well soluble in water, solution called ammonia. PH3 stands for Phosphine. Phosphine is a toxic gas that is colorless, but is flammable
  4. i looked up in the back of the book and found the Kb of CH3NH2 to be 4.4 X 10^-4. do i put this number in for the question mark up above or do i have to do that Ka=Kw/Kb thing
