15 Facts on H2SO4 + Sr: What, How To Balance & FAQs

H₂SO₄ is an acid and dehydrating agent. Strontium (Sr) is an alkaline earth metal and reactive. Let us put some light on H₂SO₄ + Sr reaction.

H₂SO₄ and Sr react to form a salt and gas is released. Sr is a soft silvery and yellowish metallic element with high reactivity. The atomic number of Strontium is 38 and it belongs to group 2 of the periodic table. H₂SO₄ is the strongest dehydrating agent with the exception of P₂O₅.

This article will help in understanding facts about H₂SO₄ + Sr reaction like reaction type, chemical equation, products formed and intermolecular forces.

What is the product of H₂SO₄ and Sr

Celestine (SrSO₄) and H₂ are the products of the H₂SO₄ + Sr reaction.

Sr + H₂SO₄ = SrSO₄ + H₂

What type of reaction is H₂SO₄ + Sr

H₂SO₄ + Sr is a single displacement reaction.

How to balance H₂SO₄ + Sr

H₂SO₄ + Sr reaction should be balanced in the following steps,

• The general chemical equation for H₂SO₄ + Sr is
• Sr + H₂SO₄ = SrSO₄ + H₂
• To check whether the number of individual atoms on the reactant and product side are the same or not. In this case, the number of atoms is the same; thus, the equation is already balanced.
• Therefore, the balanced chemical equation is,
• Sr + H₂SO₄ = SrSO₄ + H₂

H₂SO₄ + Sr titration

In H₂SO₄ + Sr reaction the titration is impossible because H₂SO₄ is an acid but, Sr is an elementary metal that cannot be titrated through any process.

H₂SO₄ + Sr net ionic equation

H₂SO₄ + Sr reaction net ionic equation is,

Sr (s) + 2H⁺ (aq.) + SO₄^2- (aq.) = SrSO₄ (s) + H₂ (g)

• Write the balanced general chemical equation
• Sr + H₂SO₄ = SrSO₄ + H₂
• Indicate the states of each molecule included in the chemical equation
• Sr (s) + H₂SO₄ (aq.) = SrSO₄ (s) + H₂ (g)
• Split the strong electrolytes into their ionic forms to obtain the net ionic equation
• Sr (s) + 2H⁺ (aq.) + SO₄^2- (aq.) = SrSO₄ (s) + H₂ (g)

H₂SO₄ + Sr conjugate pairs

The H₂SO₄ and Sr pair itself does not have any conjugate pairs,

• Conjugate pair of H₂SO₄ is its conjugate base HSO₄^–.
• The conjugate pair of Sr does not exist.

H₂SO₄ and Sr intermolecular forces

H₂SO₄ + Sr reaction has the following intermolecular forces,

• The intermolecular force between H₂SO₄ is hydrogen bonding. That is why sulphuric acid is readily soluble in water.
• Sr contains metallic bonds.
• H₂ gas has dipole-dipole interaction.
• SrSO₄ is an ionic compound therefore, ionic interactions are present between them.

H₂SO₄ + Sr reaction enthalpy

The enthalpy of reaction for H₂SO₄ + Sr is -543.8 kJ/mol. The standard enthalpy of formation for the reactants and products are:

Molecules	Reaction enthalpy (in kJ/mol)
H2SO4	-909.27
Sr	0
SrSO4	-1453.1
H2	0

Δ_fH: Standard enthalpy of formation of products – Standard enthalpy of formation of reactants

Δ_fH: [ -1453.1 -0] – [-909.27]

Δ_fH: -543.8 kJ/mol

Is H₂SO₄ + Sr a buffer solution

H₂SO₄ + Sr reaction is not a buffer solution because there should be a weak acid for a buffer solution, whereas H₂SO₄ is a strong acid.

Is H₂SO₄ + Sr a complete reaction

H₂SO₄ + Sr reaction is a complete reaction and the product formed are Celestine (SrSO₄) and H₂.

Is H₂SO₄ + Sr an exothermic or endothermic reaction

H₂SO₄ + Sr reaction is an exothermic reaction because the enthalpy of reaction has a negative value.

Is H₂SO₄ + Sr a redox reaction

H₂SO₄ and Sr reaction is a redox reaction where Sr is getting oxidized and hydrogen is getting reduced.

Is H₂SO₄ + Sr a precipitation reaction

H₂SO₄ + Sr reaction is a precipitation reaction and the precipitate of Strontium is formed which is silvery white in colour.

Is H₂SO₄ + Sr reversible or irreversible reaction

H₂SO₄ + Sr reaction is an irreversible reaction because the precipitates and the gas evolved during the progress of the reaction cannot be reverted back.

Is H₂SO₄ + Sr displacement reaction

H₂SO₄ + Sr reaction is a single displacement or substitution reaction where Strontium replaces H₂ from sulphuric acid (H₂SO₄) to SrSO₄ and releases H₂ gas.

Conclusion

This article concludes that Sr has a strong affinity to form a salt when reacting with H₂SO₄. Sr is an alkaline earth metal, meaning it has some basic character in its chemical properties. It may have several industrial importance.
