what is the oxidation # of Nitrogen in NO2^-<\/p>\n\n\n\n
The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n
To determine the oxidation state of nitrogen (N) in NO2\u2212\\text{NO}_2^-NO2\u2212\u200b, we follow these steps:<\/p>\n\n\n\n
Step 1: Assign known oxidation states<\/h3>\n\n\n\n
\n
Oxygen (O) is typically assigned an oxidation state of \u22122-2\u22122 in compounds, except in peroxides or when bonded to fluorine.<\/li>\n\n\n\n
The overall charge on the NO2\u2212\\text{NO}_2^-NO2\u2212\u200b ion is \u22121-1\u22121, meaning the sum of the oxidation states of the atoms in the ion must equal \u22121-1\u22121.<\/li>\n<\/ul>\n\n\n\n
Step 2: Set up the equation<\/h3>\n\n\n\n
The ion NO2\u2212\\text{NO}_2^-NO2\u2212\u200b consists of one nitrogen atom and two oxygen atoms. Let the oxidation state of nitrogen be xxx.<\/p>\n\n\n\n
\n
The oxidation state of each oxygen is \u22122-2\u22122, so for two oxygen atoms, the total contribution is 2\u00d7(\u22122)=\u221242 \\times (-2) = -42\u00d7(\u22122)=\u22124.<\/li>\n\n\n\n
The total charge on the ion is \u22121-1\u22121, so the equation for the sum of the oxidation states is:<\/li>\n<\/ul>\n\n\n\n
Now, solve the equation for xxx:x\u22124=\u22121x – 4 = -1x\u22124=\u22121x=\u22121+4=+3x = -1 + 4 = +3x=\u22121+4=+3<\/p>\n\n\n\n
Conclusion<\/h3>\n\n\n\n
The oxidation state of nitrogen in NO2\u2212\\text{NO}_2^-NO2\u2212\u200b is +3+3+3.<\/p>\n\n\n\n
Explanation<\/h3>\n\n\n\n
The oxidation number of nitrogen in this ion is determined by the rule that the sum of the oxidation states in a compound or ion must equal the overall charge. Since each oxygen atom is assigned a typical oxidation state of \u22122-2\u22122, and the total charge on the ion is \u22121-1\u22121, nitrogen must have an oxidation state of +3+3+3 to balance the equation. Thus, nitrogen in NO2\u2212\\text{NO}_2^-NO2\u2212\u200b is oxidized to an oxidation state of +3+3+3.<\/p>\n\n\n\n<\/figure>\n","protected":false},"excerpt":{"rendered":"
