WebChloroform is used as a solvent, a substance that helps other substances dissolve. Also, it is used in the building, paper and board industries, and in pesticide and film production. It … WebWhen the solubility of a compound formed during titration is too high, nonaqueous or mixed solvents are used, for example, when sulfates are titrated with lead (II) using a lead ion-selective electrode. In this case water-ethanol solvent is used. Table 2 presents some examples of potentiometric precipitation titrations. Table 2. WebIndeed, the most commonly used solvents in the electrospinning field are halogenated ( e.g. chloroform, trifluoroethanol) and toxic solvents ( e.g. dimethylformamide), the use of which is now restricted by the Chemical Control Regulation in the European Union (REACH). bang olufsen mac
