  1. Correct Answer – A
    Bleaching powder is `Ca(OCI)CI`. It contains `OCI^(-)` ion and the corresponding acid is HCIO. The anhydride of HCIO is :
    `underset(HOCI)overset(HOCI)(+) to H_(2)O + CI_(2)O`

  1. Correct Answer – A
    Bleaching powder` to CaOCl_(2)`
    `to Ca^(2+)(Ocl^(-))(Cl^(-))`
    It is salt of hypochlorous acid HOCl, Anhydride of HOCl is `Cl_(2)O`
    `2HOCl to Cl_(2)O+H_(2)O`

  1. Correct Answer – A
    `CaOCl_(2)=Ca(OCl)Cl`
    `OCl^(-) rarr` Hypochlorite ion
    which is anion of `HOCl`
    Anhydride of `HOCl=Cl_(2)O`

Bleaching powder and bleach solution are produced on a large scale and used in several hous-hold products. The effectiveness of bleach solution id often measured by iodometry.
`25 mL` of household bleach solution was mixed with `30 mL` of `0.50 M KI` and `10 mL` of `4N` acetic acid. In the titration of the liberated iodine, `48 mL` of `0.25 N Na_(2)S_(2)O_(3)` was used to reach the end point. The molarity of the household bleach solution is :
A. 0.48 M
B. 0.96 M
C. 0.24 M
D. 0.024 M

  1. Correct Answer – C
    Milli mole of Hypo `=0.25xx48`
    `=2xx` milli moles of `Cl_(2)`
    milli mole of `Cl_(2)=(0.25xx48)/2=6` milli mole of `CaOCl_(2)`
    = milli mole of `Cl_(2)=` milli mole of `CaOCl_(2)`
    So, molarity `=6/25 M=0.24 M`.
