what is the oxidation number of Pb in Pb(NO3)2<\/p>\n\n\n\n

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

The oxidation number of lead (Pb) in Pb(NO3)2 is +2.<\/p>\n\n\n\n

To explain this, let’s break it down:<\/p>\n\n\n\n

    \n
  1. Nitrate ion (NO3-)<\/strong>: The nitrate ion is a polyatomic ion where nitrogen typically has an oxidation state of +5 and each oxygen has an oxidation state of -2. Since the ion as a whole has a charge of -1, the sum of the oxidation numbers in NO3- must be -1.<\/li>\n<\/ol>\n\n\n\n
      \n
    • Nitrogen: +5<\/li>\n\n\n\n
    • Oxygen: -2 \u00d7 3 = -6<\/li>\n\n\n\n
    • Total for NO3-: +5 + (-6) = -1 (which matches the charge on the nitrate ion).<\/li>\n<\/ul>\n\n\n\n
        \n
      1. Lead (Pb)<\/strong>: In Pb(NO3)2, there are two nitrate ions, each with a charge of -1. The total negative charge from the nitrate ions is -2 (since -1 \u00d7 2 = -2). For the compound to be neutral overall, the total positive charge from lead (Pb) must balance this out. Therefore, the oxidation number of Pb must be +2 to balance the -2 charge from the nitrates.<\/li>\n\n\n\n
      2. Overall charge balance<\/strong>: The compound Pb(NO3)2 is neutral, so the sum of the oxidation numbers must be zero. The lead ion (Pb) has an oxidation number of +2, and the two nitrate ions (NO3-) each contribute a -1 charge, so:<\/li>\n<\/ol>\n\n\n\n
          \n
        • Pb: +2<\/li>\n\n\n\n
        • 2 \u00d7 NO3-: -2<\/li>\n\n\n\n
        • Total: +2 + (-2) = 0<\/li>\n<\/ul>\n\n\n\n

          Hence, the oxidation number of Pb in Pb(NO3)2 is +2. This is consistent with the general rule that lead typically has an oxidation number of +2 in ionic compounds, especially when paired with highly charged ions like nitrate.<\/p>\n","protected":false},"excerpt":{"rendered":"
