JEE (Advanced) 2012 Paper-2
Bleaching powder and bleach solution are produced on a large scale and used in several house hold products. The effectiveness of bleach solution is often measured by iodometry.
25mL of household bleach solution was mixed with 30mL of 0.50MKI and 10mL of 4N acetic acid. In the titration of the liberated iodine, 48mL of 0.25 N $$Na_2S_2O_3$$ was used to reach the end point. Themolarity of the household bleach solution is
Bleaching powder contains a salt of an oxoacid as one of its components. The anhydride of that oxoacid is
In the following reactions sequence, the compound J is an intermediate.
$$J(C_9H_8O_2)$$ gives effervescence on treatment with $$NaHCO_3$$ and positive baeyer's test
