Una muestra de 50ml de agua fue tomada de un acuífero de agua dulce para analizar la contaminación sufrida con cloruro (Cl-) proveniente de agua salada. Se utilizó el método de valoración de nitrato de mercurio de concentración 0.0258M. La muestra fue tratada con ácido, se le añadió un indicador y luego valorada hasta llegar al punto final consumiendo 3.08ml de titulante. Determine la concentración de Cl- en ppm. Reacciones:
Hg(NO3)2 = Hg^2+ + 2NO3-
2cl- + Hg^2+= HgCl2​
