19. Consider a buffer solution that contains a mixture of aqueous methyl amine (CH3NH2) and CH3NH3Cl. a. Write the net ionic equation for the reaction that occurs when a few drops of HCl are added to the solution. b. Write the net ionic equation for the reaction that occurs when a few drops of NaOH are added to the solution.
Calculate the pH of a 1.40 M CH3NH3Cl solution. Kb for methylamine, CH3NH2, is 4.4 × 10-4. Calculate the pH of a 1.40 M CH3NH3Cl solution. Kb for methylamine, CH3NH2, is 4.4 × 10-4. 1.61 8.75 5.25 12.39
Calculate the pH of a buffer solution that is 1.25 M CH3NH2 and 1.00 M CH3NH3Cl. Kb = 8.85 x 10-4 and what would happen after 35.0 mL of 0.45 M HNO3 is added to 250.0 mL of the buffer solution, what would the pH of the solution be after the HNO3(aq) is added?
Question 7 of 9 How many moles of CH3NH3Cl need to be added to 200.0 mL of a 0.500 M solution of CH3NH2 (Kb for CH3NH2 is 4.4 * 10-4) to make a buffer with a pH of 11.60? mol C +/- 0 x 100
Consider a buffered solution containing CH3NH3Cl and CH3NH2. Which of the following statements are true concerning this solution? (Ka for CH3NH3+ = 2.2 × 10-11). (Select all that apply.) A solution consisting of 2.5 M CH3NH3Cl and 2.5 M CH3NH2 would have a higher capacity than one containing 0.5 M CH3NH3Cl and 0.5 M CH3NH2. If NaOH were added to the initial buffered solution, then the [CH3NH2] would increase. Adding more [CH3NH3Cl] to the initial buffer solution will decrease the...
