(a)
Interpretation:
The given incomplete reaction needs to be completed.
Concept introduction:
The group-17 of the periodic table is also called as halogens. They are most reactive and most electronegative non-metals in the periodic table. The reactivity and electronegativity of elements decreases down in the group therefore fluorine is most reactive halogen and iodine is least reactive halogen. In other words; in displacement reactions, a more reactive halogen can displace a less reactive halogen to form product. For example, chlorine can displace bromine from its solution but vice-versa is not possible. The reactivity order for halogens is:

(b) When do you need to perform back titration? (c) Ni2+ can be analyzed by a back titration using standard Zn2+ at pH 5.5 with xylenol orange indicator. A solution containing 25.00 mL of Ni2+ in dilute HCl is treated with 25.00 mL of 0.05283 M Na2EDTA. The solution is neutralized with NaOH, and the pH is adjusted to 5.5 with acetate buffer. The solution turns yellow when a few drops of indicator are added. Titration with 0.02299 M Zn2+ requires 17.61 mL to reach the red end point.
