We know 1% sodium hypochlorite solution is being used as disinfectant during this COVID 19 pandemic. Here are the ways to prepare this solution.
| Product | Available Chlorine | 1 percent |
| Sodium hypochlorite – liquid bleach | 3.5% | 1 part bleach to 2.5 parts water |
| Sodium hypochlorite – liquid | 5% | 1 part bleach to 4 parts water |
| NaDCC (sodium dichloro-isocyanurate) powder | 60% | 17 grams to 1 litre water |
| NaDCC (1.5 g/ tablet) – tablets | 60% | 11 tablets to 1 litre water |
| Chloramine – powder | 25% | 80 g to 1 litre water |
| Bleaching powder | 70% | 7g to 1 litre water |
| Any other | As per manufacturer’s instructions |
Among these, adding 7 gm bleaching powder to 1 litre water is probably the cheapest way.
