The equation 8HNO3 + 3Pb -> 3Pb(NO3)2 + 4H2O + 6NO.

  1. Detailed information about the equation 8HNO3 + 3Pb -> 3Pb(NO3)2 + 4H2O + 6NO:

This equation describes the reaction between nitric acid (HNO3) and lead (Pb) to form lead nitrate (Pb(NO3)2), water (H2O) and nitric oxide (NO).

  1. Reaction conditions:

This reaction requires sufficient amounts of nitric acid and lead. Also, the reaction usually takes place more easily at higher temperatures.

  1. Reaction Process:

When nitric acid and lead contact each other, they begin to react to form lead nitrate, water and nitric oxide. Lead is oxidized from the oxidation state of 0 in Pb to +2 in Pb(NO3)2, while nitrogen in HNO3 is reduced from +5 to +2 in NO.

  1. Phenomena occurring:

During the reaction, one can see lead gradually dissolving in the nitric acid solution with bubbling, indicating that gas is being released. Simultaneously, the original solution will turn lighter due to the formation of lead nitrate.
