1.
If 25.0mL of an unknown sample was titrated with 0.115M NaOH andproduced the titration curve below, answer the questions belowregarding this titration.
1. The TITRANT used in thistitration would be classified as weak base, strong acid, weac acid,trong base
2. The ANALYTE used in thistitration would be classified as [ Select ] ["strong acid", "weakbase", "weak acid", "strong base"]
3. The pH at the equivalence point would be characterizedas [select]
2)
Consider the titration of 100.0mL of 0.10MNH3 with 0.10M HNO3. What is thepH of the solution after the addition of 200.0mL ofHNO3?
Kb of NH3 = 1.8 x 10-5
3)
What would be the expected pH at the half-equivalence point forthe titration of 25.0mL of 0.150M HOCl (Ka= 3.0 x 10-8)with 0.150M NaOH?
