WIte A if the statement is correct, B if the statement is wrong. 1. Redox is a process in which a proton transfer takes place. 2. The color of ferric thiocyanate precipitate is yellow. 3. Group 1A has a valence of +2. 4. For atoms in its elemental form has an oxidation number of zero. 5. Fluorine has an oxidation number of -1. 6. NH4F can be used to inactivate, mask or screen metals such as Co, Ni. Cu and Zn A7. EDTA is considered as a hexadentate molecule. A 08. The metal ions which are determined by direct titration with EDTA are Calcium, Magnesium A9. The equilibrium constant of the reaction applied to soluble complex formed is called a solu A10. The sum of oxidation number values of all the atoms in a molecule or formula unit of a cor Al1. The higher is the Ks the more stable is the complex formed.
