Tap water which is commonly used in fish pond, may contain chlorine (Cl2). To allow the fish to live healthily, the chlorine can be pre-treated using sodium thiosulfate (Na2S2Os). Removal of chlorine depends on the assumed conversion in 1 m of rectangular fish tank (pond) volume. Water (H2O) is in excess state of having 4 ppm chlorine. Referring to the findings by Cao et al. (2007). the liquid-phase reaction is zero order with respect to water whilst the rests are...
