#4: A sodium hydroxide solution is standardized using the monoprotic primary standard potassium hydrogen phthalate, KHP (204.22 g/mol). If 0.7268 g of KHP requires 53.29 mL of NaOH, what is the NaOH concentration?
Choices:
0.0449 M
0.0558 M
0.0668 M
0.0778 M
#5: Titration of 0.1212 g of pure Na2C2O4 (134 g/mol) required 19.14 mL of KMnO4. What is the molarity of the KMnO4 solution?
The net ionic equation for this reaction is:
2MnO4- + 5C2O42- + 16H+ ---> 2Mn2+ + 8H2O + 10CO2
Choices:
0.0189 M
0.0473 M
0.0722 M
0.1181 M
