Which metal sticks to a glass plate after treatment with ozone
Silver
Mercury
Copper
Lead
Number of hydroxyl groups present in pyrosulphuric acid is
3
4

2
The reaction in the Kipp's apparatus stops when the outlet is closed from the top because
The acid become weak
Gas pressure breaks the contact between FeS and the acid
Gas starts coming out
Protective film is formed on FeS
