15 Facts on H2SO4 + AgNO3: What, How To Balance & FAQs

Silver nitrate (AgNO₃) is an inorganic compound with antiseptic properties, that reacts with sulfuric acid (H₂SO₄). Let us examine the reaction between H₂SO₄ and AgNO₃ in depth.

Sulphuric acid, also known as oil of vitriol, is a strong acid that completely ionises in water. H₂SO₄ is a very hazardous acid. It is a corrosive liquid that is dense, colourless, and oily. Silver nitrate (AgNO₃) is a precursor for various silver compounds, including those employed in photography.

In this article, we will concentrate on the numerous features of the H₂SO₄ + AgNO₃  reaction in detail.

What is the product of H₂SO₄ and AgNO₃

When AgNO₃ reacts with H₂SO₄, a precipitate of silver sulphate and nitric acid are formed.

2AgNO₃(aq)+H₂SO₄(aq)→Ag₂SO₄(s)+2HNO₃(aq)

How to balance H₂SO₄ + AgNO₃

• To balance H₂SO₄ + AgNO₃, the general equation is as follows: AgNO₃(aq)+H₂SO₄(aq)→Ag₂SO₄(s)+HNO₃(aq)
• The reaction has balanced moles, meaning the number of reactant moles must equal the number of product moles.
• On the reactant side, 2 moles of AgNO₃ are added.
• On the product side, 2 moles of HNO₃ are added.
• The overall balanced reaction is as follows:
• 2AgNO₃(aq)+H₂SO₄(aq)→Ag₂SO₄(s)+2HNO₃(aq)

H₂SO₄ + AgNO₃ titration

We can titrate H₂SO₄ + AgNO₃ to determine the amount of Ag. However, the reaction should be carried out carefully because the result is a precipitate.

Apparatus used

Burette, pipette, Erlenmeyer flask, burette holder, wash bottle, dropper, volumetric flask and beakers.

Titre and titrant

In H₂SO₄ + AgNO₃ titration, sulphuric acid is used as the titrant, and the titre is AgNO₃.

Indicator

An acid-base indicator called phenolphthalein is employed to detect the titration’s end point.

Procedure

• Standardised H₂SO₄ was taken in a burette, and the AgNO₃ was taken in an Erlenmeyer flask.
• Added 1-2 drops of phenolphthalein indicator.
•  Until the solution changed from being colourless to light pink, the H₂SO₄ from the burette was added dropwise into conical flask.
• The process was repeated to obtain three concordant readings.

H₂SO₄ + AgNO₃ net ionic equation

H₂SO₄ + AgNO₃ reaction has the following net ionic equation,

• 2Ag⁺(aq)+2NO₃^–(aq)+2H⁺(aq)+SO₄^2-(aq) → Ag₂SO₄(s)+2H⁺(aq)+2NO₃^–(aq).

H₂SO₄ + AgNO₃ conjugate pairs

H₂SO₄ + AgNO₃ reaction do not form conjugate pairs because they do not undergo conjugation to produce the desired products.

H₂SO₄ and AgNO₃ intermolecular forces

The intermolecular forces present in H₂SO₄ and AgNO₃ are as follows,

• Dipole-dipole interactions, Van der Waal’s dispersion, and hydrogen bonding are the intermolecular forces in H₂SO₄.
• AgNO₃ is an ionic compound. It exhibits ion-dipole interactions.

H₂SO₄ + AgNO₃ reaction enthalpy

H₂SO₄ + AgNO₃ standard reaction enthalpy of the reaction is -124.39032 kJ/mol, and here the change in enthalpy is negative.

Is H₂SO₄ + AgNO₃ a buffer solution

H₂SO₄ + AgNO₃ reaction will not form a buffer solution because H₂SO₄ is a strong acid.

Is H₂SO₄ + AgNO₃ a complete reaction

H₂SO₄ + AgNO₃ reaction is complete because silver chloride and nitric acid are produced in about equal amounts and do not undergo further reaction.

Is H₂SO₄ + AgNO₃ an exothermic or endothermic reaction

H₂SO₄ + AgNO₃ reaction is exothermic. As a result, this heat will be required to complete the reaction.

Is H₂SO₄ + AgNO₃ a redox reaction

H₂SO₄ + AgNO₃ reaction is not a redox reaction, as there is no change in the oxidation state of the reactants or products.

Is H₂SO₄ + AgNO₃ a precipitation reaction

H₂SO₄ + AgNO₃ reaction is a precipitation reaction as silver sulphate (Ag₂SO₄) is the precipitate formed.

Is H₂SO₄ + AgNO₃ reversible or irreversible reaction

H₂SO₄ + AgNO₃ reaction is irreversible since the products formed don’t combine to reform reactants.

Is H₂SO₄ + AgNO₃ displacement reaction

H₂SO₄ + AgNO₃ reaction is a double displacement reaction because the cations and anions exchange to produce the water and the salt.

Conclusion

This article summarises the reaction between H₂SO₄ + AgNO₃ as an acid-base, neutralisation, double displacement and precipitation reaction. The reaction has a negative enthalpy. The products are displaced twice and are irreversible.
