Question

why does odonil disappear in few days?​

Answer 1

Answer:

THIS IS BECAUSE ODONIL TABLETS UNDER GO SUBLIMATION. THE ODONIL TABLETS KEEP ON FORMING ODONIL VAPOURS SLOWLY, WHICH DISAPPEAR INTO THE AIR. Odonil is a sublimable substance i.e. it will convert into gaseous state without converting into water. so it will disappear.
