Question

amount of bleaching powder required to disinfect 1 litre of water​

Answer 1

To make this, mix 15 gram bleaching powder with 100 ml (half glass) water and keep for 15-20 minutes. Clear water derived from this could be used as chlorine solution. To purify drinking water from bacteria, add 8 drops (0.5 ml) of chlorine solution in 1 litre of water to purify it.
