When concentrated HCl is added drop wise to the solid potassium permanganate, chlorine gas is liberated the liberated gas is collected in separate bottles by the upward displacement of air.
- Developmental Questions (What discussion questions)
1.The liberated gas is collected using a gas jar by the upward
displacement of air. Why?
2.Thistle funnel should be dipped in the acid, why?
