1. Calculate using the potentiometric method by acid-base titration the value of the equivalence point potential (Eeq) and the potential jump ΔE 99.9% - 100.1% titration if an acid solution of unknown concentration (Cx, mol/l) is titrated with a NaOH solution (0, 1 mol/l). Neglect dilution and diffusion potential.
Cell:
Ag |quinhydrone electrode | acid (Cx, mol/l) || KCl 1 mol/l AgCl| Ag
where titratable acids: 1) HNO2; 2) HCOOH; 3) HNO3.
