Question

$\textbf{Reduction potential of ions are given below:}$
\[ \begin{array}{ccc} \text{ClO}_4^- & \text{IO}_4^- & \text{BrO}_4^- \\ E^\circ = 1.19 \, \text{V} & E^\circ = 1.65 \, \text{V} & E^\circ = 1.74 \, \text{V} \\ \end{array} \]
The correct order of their oxidising power is:

Answer 1

Red lead, chemically Pb$_3$O$_4$, is a common lead compound.
It's also called trilead tetraoxide or minium, and is a bright red or orange-red powder.
Structure and Composition:
Pb$_3$O$_4$ is a mixed oxide with both Pb(II) and Pb(IV) oxidation states.
It's a combination of 2 moles of PbO (lead(II) oxide) and 1 mole of PbO$_2$ (lead(IV) oxide):\n \[ \text{Pb}_3\text{O}_4 \rightarrow 2\text{PbO} + \text{PbO}_2 \]\n Applications:
Red lead is used in rust-proof primer paints for iron and steel.
It's also used in storage batteries and glass manufacture.\n Hence, the correct answer is Pb$_3$O$_4$.
