Advantages of using mercury as a barometric liquid.
1. Since density of mercury is more than that of water, less height of mercury coloumn (0.76m of Hg) is needed to balance normal atmospheric pressure.
2. Since the vapour pressure is negligible, the torricelli vacuum doesn't affect the barometric height.
3. It can easily be obtained into a pure state.
