Using the Handerson-Hasslebalch Equation, what is the pH of the solution?
Ka= 0.0004
A- = 0.0001
HA = 0.0035
pH = pKa + log10 (A-/HA)
1.85
Solution:
pH = pKa + log10 (A-/HA) = -log(0.0004) + log (0.0001/0.0035)
Using the Handerson-Hasslebalch Equation, what is the pH of the solution?
Ka= 0.0008
A- = 0.002
HA = 0.0045
pH = pKa + log10 (A-/HA)
2.75
Solution:
pH = pKa + log10 (A-/HA) = -log(0.0008) + log (0.0002/0.0045)
Using the Handerson-Hasslebalch Equation, what is the pH of the solution?
Ka= 0.0007
A- = 0.001
HA = 0.0015
pH = pKa + log10 (A-/HA)
2.98
Solution:
pH = pKa + log10 (A-/HA) = -log(0.0007) + log (0.001/0.0015)
Using the Handerson-Hasslebalch Equation, what is the pH of the solution?
Ka= 0.0009
A- = 0.0015
HA = 0.0015
pH = pKa + log10 (A-/HA)
3.05
Solution:
pH = pKa + log10 (A-/HA) = -log(0.0009) + log (0.0015/0.0015)
