Thymolphthalexone
WebbAt the stoichiometric point of the titration of aqueous ammonia with hydrochloric acid, the solute is ammonium chloride. Because NH4+ is an acid, we expect the solution to be acidic with a pH of less than 7. The same is true for the stoichiometric point of the titration of any weak base and strong acid. [Pg.663] Webb15 dec. 2011 · The proposed method is based on the adsorptive accumulation of thymolphthalexone complexes of these elements onto a hanging mercury drop electrode, followed by reduction of adsorbed species by voltammetric scan using differential pulse modulation.
