Yellow compound of lead chromate gets dissolved on treatment with hot NaOH solution. The product of lead formed is a:
Updated On: Mar 21, 2025
- Tetraanionic complex with coordination number six
- Neutral complex with coordination number four
- Dianionic complex with coordination number six
- Dianionic complex with coordination number four
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The reaction of lead chromate with NaOH (in hot, excess conditions) results in the formation of a soluble dianionic complex:
PbCrO4 + NaOH (hot, excess) → [Pb(OH)4]2- + Na2CrO4
The product [Pb(OH)4]2- is a dianionic complex with a coordination number of four.
