Reaction of lead oxide with nitric acid?

Answer 1

The actual reaction is:

Pb(s) + 4HNO3(aq) -----> Pb(NO3)2(aq) + 2H2O(l) + 2NO2(g)

This is interesting for a number of reasons. Since the activity of lead is less than H2, (The Eo for the reduction of Pb2+ to the metal is -0.125 V, compared to the minimum -0.6 V or less that is required) the reaction cannot occur as a single replacement, e.g.

Pb(s) + 2HNO3(aq) -----> Pb(NO3)2(aq) + H2(g) does not occur. There are really two reactions at work.

1.) HNO3 oxidizes Pb to form PbO:

Pb(s) + 2HNO3(aq) -----> PbO(s) + H2O(l) + 2NO2(g)

Lead is oxidized from 0 to +2 and two moles of N are reduced from +5 to +4. This is a redox reaction.

2.) HNO3 then reacts with PbO and to form Pb(NO3)2:

PbO(s) + 2HNO3(aq) -----> Pb(NO3)2(aq) + H2O(l)

This is a double replacement reaction. This sequence of events is seen (albeit with a change in stoichiometry) for other some other metals as well, most notably copper and silver.

Answer 2

2HNO3 + PbCO3= Pb(NO3)2 + CO2 + H2O

- Balanced the equation

Answer 3

Assuming an ideal metal acid reaction.

Pb + 2HNO3 --> Pb(NO3)2 + H2

Answer 4

Pb(NO3)2 + 2HCl = PbCl2 + 2HNO3 ... white ppts of lead chloride are formed....

Answer 5

Lead plus nitric acid equals lead nitrate and hydrogen gas. Lead react very slowly with a dilute acid such as nitric acid.

Answer 6

2 HNO3 (aq) + PbO (s) ---> Pb(NO3)2 (aq) + H2O (l)

Answer 7

Aqueous Nitric acid solution reacts with solid Lead (II) oxide to yield aqueous solution of Lead (II) nitrate and Water .

Answer 8

When lead oxide reacts with nitric acid, lead nitrate and water are formed. The balanced chemical equation for this reaction is: PbO + 2HNO3 → Pb(NO3)2 + H2O
