Answer» Solution :a) The skeleton equation is written as `Cl_(2)+NaOHrarrNaCl +NaOCl+H_(2)O` B) Focusing on the oxidation numbers `overset(0)(Cl_(2))+overset(+1)(Na)overset(-2)(O)overset(+1)(H)RARROVERSET(+1)(Na)overset(-1)(Cl)+overset(+1)(Na)overset(-2)(O)overset(+1)(Cl)+overset(+1)(H_(2))overset(-2)(O)` c) LOCATING atoms undergoing change in oxidation numbers `overset(0)(Cl_(2))+NaOHrarrNaoverset(-1)(Cl)+NaOoverset(+1)(Cl)+H_(2)O` d) Determining the change in oxidation numbers E) Cris - crossing these change in the oxidation numbers `Cl_(2)+NaOHrarr NaCl +NaOCl+H_(2)O` F) Balancing the atoms other than hydrogen and oxygen `Cl_(2)+2NaOHrarrNaCl +NaOCl+H_(2)O` This is the balanced equation. |
