Chlorine forms oxides such as Cl₂O, ClO₂, Cl₂O₆ and Cl₂O₇. Chlorine and oxygen do not combine directly, so these oxides are prepared indirectly. Cl₂O is prepared by passing Cl₂ through freshly prepared yellow HgO. Cl₂O₆ disproportionates: Cl₂O₆ + 2KOH → KClO₃ + KClO₄ + H₂O. These oxides are acidic; Cl₂O₇ is the anhydride of perchloric acid.
P is the anhydride of the oxyacid whose anion is present in bleaching powder. Q is the iodine oxide formed by reacting solid N₂O₅ with iodine. Find the total number of atoms in P and Q.
Answer:
10.00
Solution:
Bleaching powder contains OCl⁻; its oxyacid is HOCl, so P = Cl₂O.
The iodine oxide is Q = I₂O₅. Atoms: Cl₂O has 3 and I₂O₅ has 7. Total = 10.
