Discover The 15 Incredible Facts On H2SO3 + Ag2S Reaction

Silver sulfide is the only sulfide of silver available. It is a black dense solid and is insoluble in most solvents. Let us see how Ag₂S reacts with H₂SO₃ in this article.

H₂SO₃ is an unstable compound that mostly exists in gaseous form and the aqueous form is currently unidentified. Ag₂S is an ionic compound of silver and sulfur. It occurs naturally as tarnishes on silver surfaces.

We will discuss the facts of the H₂SO₃ + Ag₂S reaction, like redox reaction, balanced chemical equation, net ionic equation and intermolecular forces in this article.

What is the product of H₂SO₃ and Ag₂S

Silver sulfite (Ag₂SO₃) and hydrogen sulfide (H₂S) are the products of the H₂SO₃ and Ag₂S reaction. The chemical equation for this reaction is,

H₂SO₃ + Ag₂S = Ag₂SO₃ + H₂S

What type of reaction is H₂SO₃ + Ag₂S

H₂SO₃ + H₂S reaction is a double displacement reaction.

How to balance H₂SO₃ + Ag₂S

The balanced chemical equation for H₂SO₃ + Ag₂S reaction is,

H₂SO₃ + Ag₂S = Ag₂SO₃ + H₂S

The steps mentioned below must be used to derive the balanced chemical equation:

• The general unbalanced equation for the reaction is,

• H₂SO₃ + Ag₂S = Ag₂SO₃ + H₂S

• The number of moles atoms on each side of the equation is,

Atom	Number on reactant side	Number on product side
H	2	2
S	2	2
O	3	3
Ag	2	2

• As the number of moles of each atom is already equal; therefore, there is no need to balance the chemical equation.

• Thus, the balanced chemical equation is,

• H₂SO₃ + Ag₂S = Ag₂SO₃ + H₂S

H₂SO₃ + Ag₂S titration

The titration between H₂SO₃ and Ag₂S is not favourable as H₂SO₃ is a weak acid and Ag₂S also has an acidic character.

H₂SO₃ + Ag₂S net ionic equation

The net ionic equation for H₂SO₃ and Ag₂S reaction is,

2H⁺ (aq.) + SO₃^2- (aq.) + Ag₂S (s) = Ag₂SO₃ (s) + H₂S (g)

The steps for obtaining a net ionic equation are:

• Write the balanced chemical equation.

• H₂SO₃ + Ag₂S = Ag₂S+ H₂S

• Indicate the chemical state of each compound (s, l, g or aq.) and split the strong electrolytes into ions.

• 2H⁺ (aq.) + SO₃^2- (aq.) + Ag₂S (s) = Ag₂SO₃ (s) + H₂S (g)

• Eliminate all the spectator ions to obtain the net ionic equation.

• 2H⁺ (aq.) + SO₃^2- (aq.) + Ag₂S (s) = Ag₂SO₃ (s) + H₂S (g)

H₂SO₃ + Ag₂S conjugate pairs

H₂SO₃ and Ag₂S do not contribute to any conjugate pair while the conjugate pair of H₂SO₃ is its conjugate base HSO₃^–.

H₂SO₃ + Ag₂S intermolecular forces

The interaction between H₂SO₃ and Ag₂S contains the following intermolecular forces.

• The intermolecular forces of attraction in H₂S are dipole-dipole interaction.

• Hydrogen bonding is available in H₂SO₃.

• Ionic bonding is present in Ag₂S molecules.

H₂SO₃ + Ag₂S reaction enthalpy

H₂SO₃ + Ag₂S reaction enthalpy is -490.78 kJ/mol. The reaction enthalpy is calculated using standard enthalpy of formation of reactants and products, which is as follows:

Molecules	Enthalpy of reaction (in kJ/mol)
H2SO3	-635.55
Ag2S	-31.8
Ag2SO3	-490.78
H2S	-20.63

Reaction enthalpy (ΔH_f) = Standard enthalpy of formation (Products – reactants)

ΔH_f = (-490.78 – 20.63) – (-635.55 – 31.8)

Thus, ΔH_f = -490.78 kJ/mol.

Is H₂SO₃ + Ag₂S a buffer solution

H₂SO₃ + Ag₂S do not form a buffer solution because there is no conjugate base available for H₂SO₃ in the reaction.

Is H₂SO₃ + Ag₂S a complete reaction

H₂SO₃ + Ag₂S reaction is a complete reaction; the solid products formed do not react further.

Is H₂SO₃ + Ag₂S an exothermic or endothermic reaction

The H₂SO₃ + Ag₂S reaction is an exothermic reaction because the reaction enthalpy value is negative.

Is H₂SO₃ + Ag₂S a redox reaction

H₂SO₃ + Ag₂S reaction is not a redox reaction because the oxidation state of each atom is stable through the process.

Is H₂SO₃ + Ag₂S a precipitation reaction

H₂SO₃ + Ag₂S reaction is a precipitation reaction and white crystalline precipitates of Ag₂SO₃ are obtained.

Is H₂SO₃ + Ag₂S reversible or irreversible reaction

H₂SO₃ + Ag₂S reaction is an irreversible reaction because the H₂S gas, once evolved cannot be reverted and also the reaction path has only one way.

Is H₂SO₃ + Ag₂S displacement reaction

H₂SO₃ + Ag₂S reaction is a double displacement reaction in which H and Ag atoms displace each other from their respective compounds to generate new products.

Conclusion:

In the end, we can conclude that H₂SO₃ and Ag₂S are unstable compounds available in small quantities. The Ag₂S breaks down into silver dithionate and silver sulfate to become stable. The reactions proceed with the evolution of heat.
