Notes:
- one cup is 200ml, one tablespoon is 10ml (or 14-15 g).
- Chlorine can corrode and damage metals. Therefore, it is important to never prepare chlorine solutions in metallic containers (unless they are properly enamelled or painted) or use metallic spoons for measurement or stirring. The recommendation is to use plastic containers for preparation of chlorine solutions and wooden spoons for measurement and stirring.
