- B Both and are true but is not a correct explanation for
- C is true, is false
- D is false, is true
Answer & Solution
Correct Answer
(C) is true, is false
Step-by-step Solution
Detailed explanation
The colour of old lead paintings can be restored by washing them with a dilute solution of H2O2. The reaction is given below i.e. PbOLitharge→H2SPbSBlack→H2O2PbSO4White Here, hydrogen peroxide acts as oxidising agent because oxidation state of sulphur changes from -2…
