The effectiveness of bleach solution is often measured by iodometry.
$1.$ $25 mL$ of household bleach solution was mixed with $30 \ mL$ of $0.50 \ M \ KI$ and $10 \ mL$ of $4 \ N$ 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
$(A)$ $0.48 \ M$ $(B)$ $0.96 \ M$ $(C)$ $0.24 \ M$ $(D)$ $0.024 \ M$
$2.$ Bleaching powder contains a salt of an oxoacid as one of its components. The anhydride of that oxoacid is
$(A)$ $Cl _2 O$ $(B)$ $Cl _2 O _7$ $(C)$ $ClO _2$ $(D)$ $Cl _2 O _6$
Give the answer question $1$ and $2.$
