The oxidation numbers of O and H change, depending on what compound they're in. Title: The oxidation number of a Group VIIA element in a compound is -1, except when that element is combined with one having a higher electronegativity. You can specify conditions of storing and accessing cookies in your browser, sunny bro mere questions check na karo read bhi na karo mujhe apse baat nhi karni abhi tak bhabhi se nhi milwaya â, 5. Remember that O is more electronegative so it should be the negative one between it and Cl. HClO + 2e-+ H + = Cl- + H 2 O E 0 = 1.521 V. ClO-+ 2e-+ 2H + = Cl- + H 2 O E 0 = 1.747 V So we get H^+ and Cl^-. Since the atom as whole is neutral, following equation holds true: The sum of the oxidation numbers of all of the atoms in a neutral compound is 0. The disinfection process occurs through reduction of HOCl or ClO - to Cl-with coupled oxidation of organic matter. N is the more electronegative of these two elements, and the common negative oxidation state of N is -3 ( as in NH3). ClO2 ==> Cl+4.
