Questions and Answers

What is the type of argentometric precipitation titration discussed in the lecture?

  • Mohr's Method
  • Volhard’s Method
  • Fajans’ Method
  • None of the above (correct)

    • What is used as the indicator in this argentometric precipitation titration?

  • H2SO4 solution
  • K2CrO4 solution (correct)
  • NaCl solution
  • KOH solution

    • At what pH range should the titration be performed and why?

  • pH 7 to maintain neutrality
