1.	Convert 4%w/v solution of sodium hypochlorite into 1%
Answer» Explanation: This depends on the chlorine demand, which is that water can exist Iron (II), MANGANESE, ORGANIC matter and ammonia, then their presence may consume chlorine and previously should evaluate how much chlorine is consumed and depending on bond this remnant is added regularly the minimum value recommended FREE chlorine is 0.3 mg / L, this after having reached the breaking point, which is where you will START to measure free chlorine. As comments Cotruvo consider necessary contact time and a minimum half hour is recommended, however this depends UPON the desired microorganism inactivation, as in the case of Giardia is necessary to contact two hours.
