We shall construct an ICF Chart first:
We shall construct an ICE Chart based on the following reactions with water:
HB+ + H2O ⇌ B + H3O+
Calculate the concentrations:
Total volume = 100 mL WB + 40 mL HNO3 = 140 mL
A student dissolves 0.0100 mole of an unknown weak base in 100.0 mL water and titrates the solution with 0.100 M HNO3. After 40.0 mL of 0.100 M HNO 3 was added, the pH of the resulting solution was 8.00. Calculate the Kb value for the weak base.
