Objectives

  • Make a calibration curve for the determination of Ag+ in solutions.
    • Make 0.10 M AgNO3 solution.

0.1 M AgNO3 Solution

  • Calculations 
  250 mL of 0.1 M AgNO3
  MW AgNO3 = 169.87 g/mol
  0.1 M × 0.250 L = 0.025 mol
  0.025 mol AgNO3 × (169.87 g AgNO3/1 mol AgNO3) = 4.24675 g AgNO3
  • Actual mass AgNO3: 4.24694 g
  • Actual molarity AgNO3: 0.10000 M AgNO3

Ag+ Ion Selective Electrode Calibration

  • The protocol from 2013/02/12 was followed using solutions of the following [AgNO3]:
    • 0 M AgNO3
    • 0.0001 M AgNO3
    • 0.0010 M AgNO3
    • 0.0105 M AgNO3
    • 0.1000M AgNO3
  • Conductivity of solutions of AgNO3
