The equation Pb + 2H2SO4 -> PbSO4 + 2H2O

  1. Detailed information about the reaction equation Pb + 2H2SO4 -> PbSO4 + 2H2O:

    • This is a chemical equation describing the reaction process between lead (Pb) and concentrated, hot sulfuric acid (H2SO4) to produce lead(II) sulfate (PbSO4) and water (H2O).
    • According to the equation, each mole of lead reacts with 2 moles of sulfuric acid to produce 1 mole of lead(II) sulfate and 2 moles of water.

  2. Reaction conditions:

    • The conditions for this reaction are that the sulfuric acid must be concentrated and hot.

  3. Reaction process:

    • Lead (Pb) after coming into contact with concentrated, hot sulfuric acid (H2SO4) will undergo a chemical reaction and transform into lead(II) sulfate (PbSO4) and water (H2O).

  4. Phenomena occur:

    • The phenomenon during the reaction can be observed as follows: the lead block will gradually corrode and vanish, and the sulfuric acid will decrease. Along with this, water vapor will be produced and lead(II) sulfate will precipitate.
