Question

In a reaction of lead oxide with carbon what are the oxidised and reduced species

Answer 1

Hey mate here's your answer

Word Equation

Lead (II) oxide + Carbon → Lead + Carbon dioxide

Formula Equation

2PbO (s) + C (s) → 2Pb (s) + CO2 (g)

Yellow lead (II) oxide (litharge) was mixed with powdered charcoal in a crucible. This was heated on a pipe-clay triangle on a tripod with a roaring bunsen flame and occasionally stirred. After 15 minutes small globules of molten lead were produced. Note : Carbon at first is partially oxidised to form carbon monoxide (PbO + C → Pb + CO) which then is involved in further reduction (PbO + CO → Pb + CO2). A mixture of gases would be expected with carbon dioxide being the dominant form.

Answer 2

Lead is reduced and Carbon is oxidised.

• The chemical reaction between lead oxide and carbon will be as follows -
• 2PbO + C --> 2Pb + CO2
• In the reaction, PbO is lead oxide, C is carbon, Pb is lead and CO2 is carbon dioxide.
• In the reaction, Lead loses oxygen. So, it is being reduced.
• Carbon gains oxygen and hence it is the element being oxidized in the reaction.
