15 Facts on H2SO4 + Pb(NO3)2: What, How To Balance & FAQs

H2SO4 is a strong acid, and Pb(NO3)2 is a base. Let us see the reaction of H2SO4 +Pb(NO3)2.

H2SO4 is a clear and colorless liquid that reacts with Pb(NO3)2, a white colorless solid. Pure sulfuric acid does not exist naturally on Earth due to its strong affinity to water vapor and Lead(II) nitrate must be handled with care to prevent inhalation and skin contact.

Here, in this article, we will discuss some facts about the reaction, like net ionic reaction and enthalpy of the reaction.

What is the product of H2SO4 and Pb(NO3)2

Lead Sulfate and Nitric Acid are produced in the H2SO4 + Pb(NO3)2 reaction.

H2SO4+Pb(NO3)2= Pb(SO4)+ HNO3

What type of reaction is H2SO4 and Pb(NO3)2

H2SO4 + Pb(NO3)2 is a precipitation reaction.

How to balance H2SO4 and Pb(NO3)2

The reaction H2SO4 + Pb(NO3)2 is balanced using the following steps:

H2SO4+Pb(NO3)2 = Pb(SO4)+ HNO3

  • The first thing we check is the number of atoms on the reactant and product sides.
  • After that, if the number of atoms is not the same, then we have done multiplication of the smallest figure according to the formula.
  • In the above equation, the H atom and NO3 atoms number are not the same
  • So, in this next step, we should multiply HNO3 by 2.
  • Thus the balance equation is  
  • H2SO4 + Pb(NO3)2 =  Pb(SO4) + 2 HNO3

H2SO4 and Pb(NO3)2 titration

Titration is not possible in the reaction H2SO4 + Pb(NO3)2 because H2SO4 is an acid, and when it reacts with Pb(NO3)2, it forms precipitate of Pb(SO4).

H2SO4 and Pb(NO3)2 net ionic equation

The net ionic equation for the reaction H2SO4 + Pb(NO3)2 is

Pb²+(aq)+SO₄²(aq)⇒ PbSO₄(s).

To derive the net ionic equation, following steps are followed

  • First, the soluble ionic compounds can dissociated into ions.
  • Pb²+(aq)+ 2NO₃(aq) + 2H+(aq)+SO₄²(aq) ⇒ PbSO₄(s) + 2H+(aq)+2NO₃(aq).
  • Spector ions 2NO₃ and 2H+ are cancelled out.
  • The Spector ion is 2NO₃ and 2H+.
  • Thus the net ionic equation is
  • Pb²+(aq)+SO₄²(aq)⇒ PbSO₄(s).

H2SO4 and Pb(NO3)2 conjugate pairs

  •  H2SO4 + Pb(NO3)2 doesn’t form conjugate pairs because PbSO4 is in precipitate form.
  • conjugated base of H2SO4 is HSO4.

H2SO4 and Pb(NO3)2 intermolecular forces

  • Both ionic and covalent bonds are present in Pb(NO3)2, as nitrogen and oxygen are non-metals, whereas lead is a metal.
