Na2EDTA is actually used in the lab because ____   a.  it does not lose its crystalline water component. it loses its crystalline water component thus makes a constant composition. it is a base which is needed to react with metal ions. it is easier to be dissolved in water than EDTA. it is only commercially available EDTA-related reagent.      (9). Which of the following statement is true  ? ____    a.  EDTA is an amino acid.    Usually we use the acidic form of EDTA for the lab use. EDTA stands for “ Ethyldimertetraacid” EDTA forms complexes with metal ions in a variable stoichiometry. EDTA usually offers 5 binding sites for metal ions. None of the above   (10).  “The determination of CuO ore sample” lab is a ____     a. Acid-base titration        b. complexometric titration         c. iodometry          d. gravimetry           e. iodimetry
