Yellow compound of lead chromate gets dissolved on treatment with hot

\mathrm{NaOH}

solution. The product of lead formed is a :

View answer and explanation

Correct option: D

Dianionic complex with coordination number four

Option D (Dianionic complex with coordination number four) is correct because lead chromate (

PbCrO_4

) reacts with hot NaOH to form the tetrahydroxoplumbate(II) ion, which is a dianionic complex,

[Pb(OH)_4]^{2-}

, with a coordination number of four.
