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

The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n

In sodium bicarbonate (NaHCO3), the oxidation number of carbon is +4<\/strong>.<\/p>\n\n\n\n

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

To determine the oxidation state of carbon in NaHCO3, we need to use the fact that the sum of oxidation states in a neutral compound equals zero, and the oxidation states of individual atoms follow specific rules.<\/p>\n\n\n\n

    \n
  1. Sodium (Na):<\/strong> Sodium is an alkali metal, and its oxidation number is always +1<\/strong> in compounds.<\/li>\n\n\n\n
  2. Hydrogen (H):<\/strong> In most compounds, hydrogen has an oxidation state of +1<\/strong>.<\/li>\n\n\n\n
  3. Oxygen (O):<\/strong> Oxygen generally has an oxidation state of -2<\/strong> in compounds (except in peroxides or superoxides, which do not apply here).<\/li>\n\n\n\n
  4. Bicarbonate Ion (HCO3-):<\/strong> The bicarbonate ion carries a charge of -1<\/strong>. This means the sum of the oxidation states within this ion must equal -1<\/strong>.<\/li>\n<\/ol>\n\n\n\n

    Now, let’s calculate the oxidation states within the bicarbonate ion:<\/p>\n\n\n\n

      \n
    • The oxidation state of sodium (Na) is +1<\/strong>.<\/li>\n\n\n\n
    • The oxidation state of hydrogen (H) is +1<\/strong>.<\/li>\n\n\n\n
    • The oxidation state of each oxygen (O) is -2<\/strong>.<\/li>\n\n\n\n
    • Let\u2019s assume the oxidation state of carbon (C) is x<\/strong>.<\/li>\n<\/ul>\n\n\n\n

      The sum of the oxidation states within the bicarbonate ion (HCO3-) should be equal to -1<\/strong>: +1+x+3(\u22122)=\u22121+1 + x + 3(-2) = -1<\/p>\n\n\n\n

      Simplifying this equation: +1+x\u22126=\u22121+1 + x – 6 = -1 x\u22125=\u22121x – 5 = -1 x=+4x = +4<\/p>\n\n\n\n

      Thus, the oxidation state of carbon in NaHCO3 is +4<\/strong>.<\/p>\n\n\n\n

      In conclusion, the oxidation number of carbon in sodium bicarbonate is +4<\/strong>, as determined through the balance of oxidation states in the bicarbonate ion. This calculation ensures the overall charge of the compound is neutral.<\/p>\n","protected":false},"excerpt":{"rendered":"
