When chlorine reacts with cold and dilute solution of sodium hydroxide,the products obtained are:

Three parts of $conc. HCl$ and one part of $conc. HNO_3$ are mixed to form aqua regia. It is used to dissolve:

Which is the best reducing agent?

With respect to hypochlorite,chlorate,and perchlorate ions,choose the correct statement$(s)$.
$A.$ The hypochlorite ion is the strongest conjugate base.
$B.$ The molecular shape of only the chlorate ion is influenced by the lone pair of electrons on $Cl$.
$C.$ The hypochlorite and chlorate ions disproportionate to give rise to an identical set of ions.
$D.$ The hypochlorite ion oxidizes the sulfite ion.

In the following reaction,identify the nature of the product formed by the complete hydrolysis of the underlined atom at $R.T.$:
$\underline{I}OF_5 + 2H_2O \longrightarrow HIO_4 + 5HF$

Sulphur dioxide on reaction with chlorine in the presence of charcoal gives compound $(A)$. This on reaction with white phosphorus gives $SO_2$ and compound $(B)$. The correct statement about '$B$' is
