Question

2. write the equation representing the weak base of the NH/NH.Chuffer in equilibrium with its conjugate acid 3. Write the acid-dissociation-constant, ka, for the reaction in question 12. 4. Solve for the above equation for the [H+). 5. Write the chemical equation for the reaction that occurs when HNO, solution is added to the N solution. In other words, show which species in the buffer the acid would react with 6. What happens to the [NH) and (NH4"] when HNO, is added? 7. What effect does this have on pH? 8. write the chemical equation for the reaction that occurs when NaOH solution is added to the NHI/NICI buffer solution. In other words, show which species in the buffer the base would react with 9. What happens to the (NH) and (NH4+)? 10. What effect does this have on pH?
