What is the oxidation number of carbon in NaHCO3?<\/p>\n\n\n\n

A +6<\/p>\n\n\n\n

B -4<\/p>\n\n\n\n

C +2<\/p>\n\n\n\n

D +4<\/p>\n\n\n\n

The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The oxidation number of carbon in NaHCO\u2083 (sodium bicarbonate) is +4<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

To determine the oxidation number of carbon in NaHCO\u2083, let’s follow a step-by-step approach. The general formula for sodium bicarbonate is NaHCO\u2083, which consists of sodium (Na), hydrogen (H), carbon (C), and oxygen (O).<\/p>\n\n\n\n

Step 1: Assign known oxidation numbers.<\/h4>\n\n\n\n
    \n
  • Sodium (Na)<\/strong>: Sodium is an alkali metal, and its oxidation number is always +1<\/strong> in compounds.<\/li>\n\n\n\n
  • Hydrogen (H)<\/strong>: Hydrogen typically has an oxidation number of +1<\/strong> when it is combined with nonmetals.<\/li>\n\n\n\n
  • Oxygen (O)<\/strong>: Oxygen almost always has an oxidation number of -2<\/strong> in compounds, with some exceptions (like in peroxides or when bonded to fluorine). Here, we will assume that the oxygen has an oxidation number of -2<\/strong>.<\/li>\n<\/ul>\n\n\n\n

    Step 2: Set up the equation based on the sum of oxidation numbers.<\/h4>\n\n\n\n

    In a neutral compound like NaHCO\u2083, the sum of all the oxidation numbers must equal zero. We can set up the equation for the oxidation numbers of the elements:<\/p>\n\n\n\n

    [
    \\text{Oxidation number of Na} + \\text{Oxidation number of H} + \\text{Oxidation number of C} + 3 \\times (\\text{Oxidation number of O}) = 0
    ]<\/p>\n\n\n\n

    Substitute the known values:<\/p>\n\n\n\n

    [
    (+1) + (+1) + (\\text{Oxidation number of C}) + 3 \\times (-2) = 0
    ]<\/p>\n\n\n\n

    [
    1 + 1 + x + (-6) = 0
    ]<\/p>\n\n\n\n

    Simplifying:<\/p>\n\n\n\n

    [
    -4 + x = 0
    ]<\/p>\n\n\n\n

    Solving for (x), the oxidation number of carbon:<\/p>\n\n\n\n

    [
    x = +4
    ]<\/p>\n\n\n\n

    Step 3: Conclusion.<\/h4>\n\n\n\n

    The oxidation number of carbon in NaHCO\u2083 is +4<\/strong>, which corresponds to option D<\/strong>.<\/p>\n\n\n\n

    This reasoning is based on standard oxidation state rules and the requirement that the sum of oxidation numbers in a neutral compound equals zero. Thus, the correct answer is D: +4<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
