Question

In a neutral compound, thesum of the oxidation states is zero. Note that thesign of the oxidation states and the number ofatoms associated with each oxidation state must be considered. InH2O for example, each hydrogen atom has an oxidation state of +1and each oxygen atom has an oxidation state of -2 for a total of2(+1)+(-2)=0 What is the oxidation state of an individualbromine atom in Na BrO3 What is the oxidation state of an individualnitrogen atom in NH2OH In a neutral compound, thesum of the oxidation states is zero.

Explanation / Answer

What is the oxidation state ofan individual bromine atom in Na BrO3 Let x be the oxidation number of Br Let x be the oxidation number of Br                                 +1 x   -2                                 Na BrO3     +1 + x + 3 ( -2 ) = 0                           x = +5     +1 + x + 3 ( -2 ) = 0                           x = +5 What is the oxidation state of an individualnitrogen atom in NH2OH Let y be the oxidation number of N                y +1   -2 +1                 N H2 O H     y + 2 ( +1 ) + (-2) + ( +1 ) = 0                                            y = -1 What is the oxidation state of an individualnitrogen atom in NH2OH Let y be the oxidation number of N                y +1   -2 +1                 N H2 O H     y + 2 ( +1 ) + (-2) + ( +1 ) = 0                                            y = -1
