3. Chemical Oxidation Example: Chemical quantity determination A waste stream of 20,000 gal/day contains 270 mg/L of cyanide as NaCN. Determine the theoretical (Stoichiometric) amount of chlorine required daily to destroy this waste. Atmoic weight: Na:23, C:12, N:14, CI:35.45 g/mol 2NaCN+5C12+12NaOH →Nz+Na, CO3+10NaCl+6H,0 Lamp
