I WILL RATE YOU 10 POINTS IF YOU SHOW ME HOW TO DO THIS:
For Part A: Undiluted BUffers there are three Buffers: A, B, and C
ADD HCl:
Buffer A: pH of original buffer solutions is 10.09
Volume of .100 M HCl to change pH by 1.0: .15 mL
Final pH: 9.06
Buffer B:
pH of original buffer solutions: 9.01
Volume of .100M HCl to change pH by 1.0: .15mL
Final pH: 8.07
Buffer C:
pH of original buffer: 9.09
Volume of .100 M HCl to change pH by 1.0: .63mL
final pH: 8.18
ADD NaOH:
Buffer A:
pH of original buffer solutions: 11.08
volume of .100M NaOH to change pH by 1.0 :.42mL
final pH: 12.16
Buffer B:
pH of original: 10.67
volume of .100 M NaOH change pH by 1.0: .34mL
final pH: 11.73
Buffer C:
pH original: 8.47
Volume of .100M NaOH: .26 mL
final pH:9.54
PART B: DILUTED BUFFERS
ADD HCl, same # moles as Part A:
BUFFER A:
pH of original: 10.04
Volume of .100 M HCl to change pH by 1.0: .075mL
final pH: 8.85
BUFFER B:
pH original: 8.84
volume HCl: .16mL
final pH: 1.99
ADD NaOH, same # of mol
