Silver hydroxide comes under the category of unstable species of compounds that are available in low concentrations. Let us read how AgOH and H2SO3 react with each other.
H2SO3 is a weak acid formed as an intermediate during acid rain. AgOH is unstable, which is why it is a weak acid and tends to convert into silver oxide.
We will inspect key features of the H2SO4 + Be reaction, like products, net ionic equation, conjugate pairs and intermolecular forces in this article.
What is the product of H2SO3 and AgOH
Silver sulfite (Ag2SO3) and water (H2O) are the products of the H2SO3 and AgOH reaction. The chemical equation for this reaction is,
H2SO3 + AgOH = Ag2SO3 + H2O
What type of reaction is H2SO3 + AgOH
H2SO3 + AgOH is a type of double displacement reaction.
How to balance H2SO3 + AgOH
The balanced chemical equation for H2SO3 + AgOH reaction is,
2AgOH + H2SO3 = Ag2SO3 + 2H2O
The following steps should be followed when deriving the balanced chemical equation.
- Write the unbalanced equation of H2SO3 and AgOH.
- H2SO3 + AgOH = Ag2SO3 + H2O
- Count the number of atoms from both sides of the equation. The number of atoms is found to be,
| Atoms | Number of atoms on reactant side | Number of atoms on product side |
|---|---|---|
| H | 3 | 2 |
| S | 1 | 1 |
| O | 4 | 4 |
| Ag | 1 | 2 |
- The number of atoms is not equal; therefore, we multiply AgOH and H2O with the coefficient of 2, respectively.
- Thus, the balanced chemical equation is,
- 2AgOH + H2SO3 = Ag2SO3 + 2H2O
H2SO3 + AgOH titration
Titration between H2SO3 and AgOH is not feasible as both are weak electrolytes and the pH of the solution changes gradually during the titration, making it difficult to predict the end-point by any indicator.
H2SO3 + AgOH net ionic equation
The net ionic equation for H2SO3 and AgOH reaction is,
H2SO3 (aq.) + OH– (aq.) = 2SO32- (aq.) + 2H2O (l)
The steps to obtain the net ionic equation are:
- Write the balanced chemical equation indicating the chemical state (s, l, g or aq.) of each compound.
- 2AgOH (aq.) + H2SO3 (aq.) = Ag2SO3 (aq.) + 2H2O (l)
- Strong electrolytes will split to give ions.
- H2SO3 (aq.) + 2Ag+ (aq.) + OH– (aq.) = 2Ag+ (aq.) + 2SO32- (aq.) + 2H2O (l)
- Spectator ions should be eliminated to obtain the net ionic equation.
- H2SO3 (aq.) + OH– (aq.) = 2SO32- (aq.) + 2H2O (l)
H2SO3 + AgOH conjugate pairs
H2SO3 + AgOH do not contribute to any conjugate pair and the conjugate pair of H2SO3 is HSO3–.
H2SO3 and AgOH intermolecular forces
H2SO3 and AgOH contains the following intermolecular forces of attraction:
- The intermolecular force between Ag2SO3 compounds is ionic bond.
- H2SO3 contains dipole-dipole interactions.
- Dipole-dipole interaction, London dispersion forces and hydrogen bonding are present in H2O.
H2SO3 + AgOH reaction enthalpy
H2SO3 + AgOH reaction enthalpy is -178.07 kJ/mol. The reaction enthalpy can be calculated using enthalpy of formation of compounds involved which is as follows,
| Compound | Reaction enthalpy (in kJ/mol) |
|---|---|
| H2SO3 | -635.55 |
| AgOH | -124.41 |
| Ag2SO3 | -490.78 |
| H2O | -285.83 |
Enthalpy of reaction (ΔHf) = Standard enthalpy of products – standard enthalpy of reactants
ΔHf = (-490.78 – 285.83) – (-635.55 – 124.41)
Thus, ΔHf = -178.07 kJ/mol.
Is H2SO3 + AgOH a buffer solution
H2SO3 + AgOH is not a buffer solution because no conjugate base available in correspondence to H2SO3.
Is H2SO3 + AgOH a complete reaction
H2SO3 + AgOH reaction is a complete reaction and no steps can be performed other than the mentioned one.
Is H2SO3 + AgOH an exothermic or endothermic reaction
H2SO3 + AgOH reaction is an exothermic reaction because the value of reaction enthalpy is negative.
Is H2SO3 + AgOH a redox reaction
H2SO3 + AgOH reaction is not a redox reaction as the oxidation states of atoms do not change during the reaction.
Is H2SO3 + AgOH a precipitation reaction
H2SO3 + AgOH reaction is not a precipitation reaction as no solid compound is available on the product side.
Is H2SO3 + AgOH reversible or irreversible reaction
H2SO3 + AgOH reaction is irreversible in nature because the reaction path is only one way, it cannot be performed backward.
Is H2SO3 + AgOH displacement reaction
H2SO3 + AgOH reaction is a double displacement reaction in which H and Al atoms displace each other from their respective compounds.
Conclusion:
This article concludes that both the compounds (H2SO3 and AgOH) are weak electrolytes and unstable. The evolution of heat accompanies the reaction during the progress. H2SO3 is mostly found in a gaseous state and there are doubts regarding the exitance of its aqueous form.
