WebPractice Problem: A water plant uses sodium hypochlorite (15%) to disinfect the water. Sodium hydroxide is usually added in small amounts to household bleach to slow down the decomposition of NaClO. The old tables will typically show 120 gpl available chlorine bleach with 0.73 % by weight excess caustic which results in a specific gravity of 1.168 at 20 degrees C. Typically, the sodium hypochlorite produced by a continuous process will have approximately 0.2% by weight excess sodium hydroxide and this would result in a specific gravity of 1.160.
