16. For the separation of metal ions by extraction from water solvents to organic solvents is required stages of formation of uncharged molecules, because... A. Organic solvents are more polar than water solvents B. Organic solvents can dissolve metal molecular complexes C. Uncharged molecules will be ionized in water D. Uncharged molecules do not ionize in organic solvents E. The polarity of metal ions is more like water than organic solvents 17. In a Fe(III) ion extraction process, the FeCl4 anion complex is formed which is neutralized by acid, then drawn to ether solvent. This process includes a complex formation method… A. Chelate, because the Fe(III) ion binds to the Cl- ligand to form a complex B. Ionic association, because the FeCl4 molecule is attracted to the ether solvent C. Chelate, due to the presence of acid accelerates the formation of complex ions D. Ionic association, because the FeCl4 anion combines with the H+ ion so neutral E. Chelate and ionic association, because FeCl4 complex is initially formed then join H+ 18. The basis for the separation process in electrophoresis is the distribution of .... A. Components due to differences in solubility between two immiscible liquids B. Components differentially between the liquid and solid phases. C. The solute from the solvent due to the difference in polarity D. A large molecule that is charged based on its molecular weight and type of charge. E. Charged molecules towards the positive and negative electrodes. 19. The main difference between the separation process that occurs in zone electrophoresis and capillary electrophoresis is …. A. The electric voltage used B. Direction of particulate migration C. Location of cathode and anode D. Presence of detector E. Type of supporting phase 20. The mobility of the particles to be separated by electrophoresis depends on the following, except …. A. Ionic radius B. Zeta potential C. Viscosity of solution D. The magnitude of the charge E.
