一般描述
Sodium oxalate is a water soluble inorganic salt mainly used for the standardization of permanganate solution during titration.
应用
Sodium oxalate may be used as a dispersant and a coordination agent for the electrooxidation of formic acid using a palladium nanoparticle catalyst dispersed on the purified multi-walled carbon nanotubes (P-MWCNTs). In combination with sodium hydroxide, it may be used to mediate the preparation of Cu/ZrO2catalyst from copper nitrite and zirconium nitrate solution mixture via coprecipitation method.
