The oxidation number of Cl is always -1 when it's not in diatomic form (Cl2). The chief was seen coughing and not wearing a mask. Notice that in each half reaction there is a balance both in the numbers of atoms of each kind and in the overall charge on each side. The formation was primarily attributable to SO 4 â¢â in the UV/PDS system, whereas Co(III) played a significant role in the oxidation of Cl â to HOCl/OCl â and SO 4 â¢â was important for the oxidation of HOCl/OCl â to chlorate in the Co/PMS system. A galvanic uses electrical energy to carry out a If some universal indicator is added to the solution it will first turn red due to of H = +1 O.S. +1 Firstly it's an ionic compound so Na+ and OCl-.
