Options:
A) The solution will remain colourless
B) The solution will become dark green

Show Answer
Answer:
Correct Answer: D
Solution:
$ CrO_2Cl_2\ \xrightarrow{NaOH}\ Na_2CrO_4\ \underset{CH_3COOPb}{\mathop{\xrightarrow{CH_3COOH}}} $
$ [ {{(CH_3COO)}_2}Pb ]\ \xrightarrow{CrO_2Cl_2}\ \to \ \underset{\text{yellow ppt}\text{.}}{\mathop{PbCrO_4}} $
