Assertion: `Pb^(4+)`can be reduced easily to `Pb^(2+)`.
Reason: `Pb^(2+)` is paramagnetic.

Assertion: PbI_(4) is a stable compound. Reason: Pb^(2+) ions with concentrated solution of KI forms a soluble complex.

Assertion : H_(2)O_(2) react with PbS to form PbSO_(4) . Reason : H_(2)O_(2) is weak acid

Assertion : PbI_(4) doesn't exist and converts into PbI_(2) and I_(2) spontaneously at room temperature but PbCl_(4) needs heatin to convert into PbCl_(2) and Cl_(2) . Reason : Pb^(2+) is more stable than Pb^(4+) due to inert pair effect.

Assertion : PbI_(4) doesn't exist and converts into PbI_(2) and I_(2) spontaneously at room temperature but PbCl_(4) needs heatin to convert into PbCl_(2) and Cl_(2) . Reason : Pb^(2+) is more stable than Pb^(4+) due to inert pair effect.

Assertion : PbI_(4) doesn't exist and converts into PbI_(2) and I_(2) spontaneously at room temperature but PbCl_(4) needs heatin to convert into PbCl_(2) and Cl_(2) . Reason : Pb^(2+) is more stable than Pb^(4+) due to inert pair effect.

Assertion : Pb_(2)O_(4) react with HNO_(2) and form PbO_(2) Reason: Lead is stable in +4 oxidation state.

Assertion (A): The size decreases as Pb gt Pb^(+2) gt Pb^(+4) Assertion (R): Z/e increases i.e force of attraction towards nucleous increases.
