calculating purity of TCCA from active chlorine % , Hive Newbee Forum

						I think I need some help here. Problem to be solved: I want to know the purity of a trichloroisocyanuric acid based pool chemical. The percentage of active chlorine is stated as 90-92%. After my preliminary calculations it seems this product should be like 98% TCCA. Maybe what I try is impossible, but anyway here's my calculations: M(TCCA) = 232.4094 g/mol TCCA + 3 HCl ^__> isocyanuric acid (?) + 3 Cl₂ m(3 Cl₂) = 212.718 g 212.718 g / 232.4094 g = 0,9152 = 91,52 % So, is the TCCA pure or am I way off here in my reasoning ? --psyloxy--

						chlorine % means how much chlorinating activity the compund has compared to an equal mass of chlorine. Since chlorine wastes 1/2 of itself in chlorination ( Cl2 + RH --> RCl + HCl ), even though TCCA has less chlorine, it has almost equal chlorinating power by weight. So, it seems you calculated right to me ^^ _{It's good to bee back! Don't trust your computer!!}
