original buffer solution has a pH of 4.76 diluted HCl solution and original buffer solution has a pH of 4.69 diluted NaOH solution and original buffer solution has a pH of 4.83 H20 and original buffer solution has a pH of 4.76 Calculating the pH of the buffer solution when strong base is added: 1a)Write the equation for the chemical reaction showing the neutralization of strong base (OH-) with the buffer. b)Calculate the moles of strong base and buffer components initially present when 5.00 mL of 0.100M NaOH is added to 25.0mL of buffer solution. Based on the chemical equation written above in 3a, determine the moles of each component remaining after reaction has gone to completion (before equilibrium has been re-established c)Calculate the pH of the buffer system once equilibrium has been re-established. State any simplifying assumptions and then check that the simplifying assumptions were valid. Use the Henderson-Hasselbalch equation for this calculation.
