332. Determine the concentration of NH4Cl in the solution (g/l), if by potentiometric titration of 20.0 ml of NH4CI solution with a solution of Hg2(NO3)2 with a molar concentration equivalent of 0.0500 mol/l, the following results were obtained:
VHg2(NO3)2, ml 10.0 15.0 17.0 17.5 17.9 18.0 18.1 18.5 19.0
E, mV 382 411 442 457 498 613 679 700 709
Determine the end point of titration by calculation and graphically using the first derivative.
