ecletica-355	Prasad, Saradh; de Santana, Renato Alexandre Costa; Campos, Ana Regina Nascimento; Leite, Valderi Duarte	Potentiometric and conductometric studies on the system acid-isopolytungstate and the formation of lanthanum tungstates	2007	8	.pdf	application/pdf	3513	201	61	The interaction of lanthanum nitrate with sodium tungstate solutions, at specific pH levels 8.0, 5.9 and 4.0 was also studied by pH and conductometric titrations, in aqueous and alcoholic media, with each of the reagents alternatively used as titrant. The different lanthanum tungstates were precipitated by mixing stoichio- metric amounts of lanthanum nitrate solutions with sodium tungstate solutions at specific pH levels 8.0, 5.9 and 4.0.	cache/ecletica-355.pdf	txt/ecletica-355.txt
