El cido sulfanlico (H 2 NC 6 H 4 SO 3 H) es un cido monoprctico con una K a = 5,9 x 10 -4 .
(a) Calcule el pH de la solucin obtenida al disolver 34,64 g de cido silfanlico en 1,00 L de agua.
(b) A esta solucin se aaden 25,38 g de sulfanilato de sodio (H 2 NC 6 H 4 SO 3 - Na + ). Calcular el pH de esta solucin.
(c) Si se agregan 10,00 mL de una solucin de HCl 0,200 M a la solucin preparada en la parte b, cul sera el nuevo pH?
