15 Facts on H2SO4 + Ag2O: What, How to Balance & FAQs

Rearranging molecules or ions of substance, into distinct form is called chemical reaction. Let us see, how chemical reaction takes place in case of H₂SO₄ + Ag₂O.

Silver (1) oxide is dark brown powder used for preparation of silver compounds. It is used in silver oxide batteries and also acts as an oxidizing agent. H₂SO₄ being strong acid undergoes reaction with Ag₂O giving insoluble salt.

The study on the effects of adding H₂SO₄ to Ag₂O will be described throughout this article with a chemical equation, in its balanced form.

What is the product of H₂SO₄ and Ag₂O

Silver (1) sulphate and water molecule are the product of reaction H₂SO₄ + Ag₂O.

Ag₂O + H₂SO₄ → Ag₂SO₄ + H₂O

What type of reaction is H₂SO₄ + Ag₂O

H₂SO₄ + Ag₂O is double displacement reaction.

How to balance H₂SO₄+ Ag₂O

The reaction is balanced using the following steps.

Ag₂O + H₂SO₄ → Ag₂SO₄ + H₂O

• Firstly, we have to tag both side of reaction with alphabetical coefficients.
• A Ag₂O + B H₂SO₄→ C Ag₂SO₄ + D H₂O
• Expressed coefficient are used to represent alphabetical reactants and products.
• Ag = 2A+2C, O = A+4B+4C+D, S = B+C, H = 2B+2D.
• Enter the coefficient values into the elimination method for estimation.
• Get the smallest, whole integer values from the result by simplifying it.
• A = 1, B = 1, C =1, D=1
• Thus, the balanced equation is-
• Ag₂O + H₂SO₄ → Ag₂SO₄ + H₂O

H₂SO₄ + Ag₂O titration

Titration between H₂SO₄ and Ag₂O is not possible to predict because both are oxidizing agent, so they cannot undergo acid base reaction. However, it shows possibility of redox titration with some irregularities.

H₂SO₄+ Ag₂O net ionic equation

Net ionic equation, for given reaction is

2H⁺ + O^-2 → H₂O

For deriving net ionic equation, following steps are used:

• A molecular equation should be balanced and include the phase of every compound.
• H₂SO₄(Aq) + Ag₂O(S) → Ag₂SO₄ (S) + H₂O(l)
• The aqueous salts or chemicals in the equation must be transformed into ions.
• Only the strong electrolytes should be broken down because they can completely dissociate.
• 2H⁺ + SO₄^-2 + 2Ag⁺ + O^-2 → 2Ag⁺ + SO₄^-2 + H₂O
• In order to display the species that are actually involved in the reaction, the spectator ions must be cancelled out.
• Thus, the net ionic equation is
• 2H⁺ + O^-2 → H₂O

H₂SO₄and Ag₂O conjugate pair

• H₂SO₄ [Conjugate base] =HSO₄^–
• H₂O [Conjugate acid] = H₃O⁺
• Ag₂O does not have any conjugate pairs because it is mild oxidizing agent.

H₂SO₄and Ag₂O intermolecular forces

• H₂SO₄ shows London dispersion forces because of presence of non-planarity in its molecule
• Van der Waals forces are present in Ag₂O because of general tendency of oxides to show covalent character.

H₂SO₄ + Ag₂O reaction enthalpy

The reaction enthalpy of H₂SO₄ + Ag₂O is -151.2 kJ/mol.

• The enthalpy is calculated using the formula:
• Change in enthalpy = addition of enthalpies of formation of product – addition of enthalpies of formation of reactant.
• Enthalpy change = [(-715.9) + (-280.7)] – [(-814.4) + (-31)]

= (-996.6) + (-845.4) kJ/mol
= -151.2 kJ/mol

Is H₂SO₄+ Ag₂O a buffer solution

H₂SO₄ + Ag₂O does not give buffer solution due to presence of strong H₂SO₄.

Is H₂SO₄ + Ag₂O a complete reaction

H₂SO₄ + Ag₂O is complete reaction because the reactants get completely converted to silver (1) sulphate and water molecules.

Is H₂SO₄ + Ag₂O an exothermic or endothermic reaction

H₂SO₄ + Ag₂O is exothermic in nature, as enthalpy change for this reaction is negative, indicating that heat is released.

H₂SO₄ + Ag₂O a redox reaction

H₂SO₄ + Ag₂O is not a redox reaction because the reaction does not involve any electron transfer and the oxidation states of every reacting species does not change from the reactant side to the product side.

Is H₂SO₄ + Ag₂O a precipitation reaction

H₂SO₄ + Ag₂O is a precipitation reaction because silver (1) sulphate has low solubility, it is insoluble in nature, leads to formation of precipitate.

Is H₂SO₄ and Ag₂O reversible or irreversible reaction.

H₂SO₄ + Ag₂O is irreversible reaction. The formation of white solid precipitate of Ag₂SO₄, makes reaction impossible to revert back.

Is H₂SO₄ + Ag₂O displacement reaction

H₂SO₄ + Ag₂O is a double displacement reaction, because both ions of reactants displace their place, resulting in new compound.

Conclusion

Ag₂O is used for photocatalytic degradation of organic pollutants and dyes, when reacts with H₂SO₄ leads to formation of white solid precipitate silver (1) sulphate. Ag₂SO₄ is having antimicrobial property and acts as biocide. Displacement of both ions takes place during reaction, results in liberation of heat.
