Nascent oxygen is a powerful ___(i)____ agent and this is responsible for bleaching property of ___(ii)____.

Q. Assertion :$S{O}_2$ is a bleaching agent. Reason: Nascent oxygen causes bleaching.

Q.

With the help of suitable examples, explain the property of $H_2{O}_2$ that is responsible for its bleaching action?

Q. Why is ozone a powerful bleaching agent?

Q. Bleaching powder is also called calcium chlorohypochlorite. It is a pale yellow powder and has a strong smell of chlorine. On account of formation of nascent oxygen it behaves as oxidising agent and bleaching agent. The amount of chlorine obtained from a sample of bleaching powder with excess of dilute acids or $C{O}_2$ is called available chlorine. The maximum percent of available chlorine comes to $49\%.$

$CaOC{l}_2+2C{H}_{3}COOH\to (C{H}_{3}COO{)}_{2}Ca+C{l}_2+H_{2}O$

$2Kl+C{l}_2\to 3KCl+l_2$

$l_2+2N{a}_2{S}_2{O}_3\to N{a}_2{S}_4{O}_6+2Nal$

Q. Nascent hydrogen is most powerful reducing agent than ordinary hydrogen because:
