Explain why if a bottle full of concentrated sulphuric acid is left open in the atmosphere by accident the acid starts flowing out of the bottle of its own?
If allowed to stand in the open air, it will absorb moisture from the atmosphere, which will affect its concentration. →Concentrated sulphuric acid is highly hygroscopic. It absorbs moisture from air and gets diluted. Since the volume increases, the acid starts flowing out of bottle.
