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

Sulphuric acid or H₂SO₄ appears as a colorless oily liquid, and MnS is a sulfide salt of manganese. Let us explore the several facets of the reaction between these two compounds.

Sulphuric acid is also known as the king of acids because of its huge application in manufacturing different chemicals. Manganese sulfide appears as a brown, green or red-colored powder. The crystals of MnS have a rock salt type of structure.

As we continue, all the essential features of the reaction between H₂SO₄ and MnS will come to light.

What is the product of H₂SO₄ and MnS

Manganese sulfate (MnSO₄) and hydrogen sulfide (H₂S) gas are the products of the reaction H₂SO₄ + MnS.

H₂SO₄ (aq) + MnS (s)  =  MnSO₄ (aq) + H₂S (g)

What type of reaction is H₂SO₄ and MnS

H₂SO₄ + MnS belongs to the category of displacement reaction.

How to balance H₂SO₄ and MnS

The reaction H₂SO₄ + MnS is balanced using the following steps-

H₂SO₄ + MnS  =  MnSO₄ + H₂S

• The reaction is already balanced as the number of atoms of H, S, O, and Mn are intact after the reaction.

Element	Before reaction	After reaction
H	2	2
S	2	2
O	4	4
Mn	1	1

H₂SO₄ and MnS titration

Titration between H₂SO₄ and MnS is not possible as this is a reaction between an acid with a sulfide salt producing a sulfate salt and an acid.

H₂SO₄ and MnS net ionic equation

The net ionic equation for H₂SO₄ + MnS is

2H⁺ (aq) + MnS (s) = Mn²⁺ (aq) + H₂S(g)

These are the steps to be followed to derive the net ionic equation.

• Write the respective ions only for soluble ionic compounds.
• H₂SO₄ and MnSO₄ being ionic, dissociate into cations and anions.
• The complete ionic equation is
• 2H⁺ (aq) + SO₄^2_– (aq) + MnS (s) = Mn²⁺ (aq) + SO₄^2- (aq) + H₂S (g)
• SO₄^2- ion being the spectator ion here, will be canceled from both sides.
• Thus the net ionic equation is
• 2H⁺ (aq) + MnS (s) = Mn²⁺ (aq) + H₂S(g)

H₂SO₄ and MnS conjugate pairs

• Sulfate ion (SO₄^2-) is the conjugate base of the acid H₂SO₄.
• MnS does not have a conjugate pair as it is a metal sulfide.

H₂SO₄ and MnS intermolecular forces

• H-bonding and dipole-dipole these two intermolecular forces are present in H₂SO₄ molecule where the first one is more significant.
• Electrostatic force of attraction will be there in MnS as it is ionic in nature.

H₂SO₄ and MnS reaction enthalpy

For H₂SO₄ + MnS, the reaction enthalpy value is -27.2 kJ/mole.

Compounds	Enthalpy of formation (ΔHf°) in kJ/mole
H2SO4 (aq)	-909.3
MnS (s)	-214.2
MnSO4 (aq)	-1130.1
H2S(g)	-20.6

• Reaction Enthalpy = ΣΔH_f°(products) – ΣΔH_f° (reactants)  
• =  [(-1130.2) + (-20.6)] – [(-909.3) + (-214.2)] KJ/mol
• = -27.2 KJ/mol

Is H₂SO₄ and MnS a buffer solution

H₂SO₄ + MnS cannot be a buffer solution as H₂SO₄ is a strong acid.

Is H₂SO₄ and MnS a complete reaction

H₂SO₄ + MnS is a complete reaction, as there is no further reaction once MnSO₄ and H₂S are formed.

Is H₂SO₄ and MnS an exothermic or endothermic reaction

H₂SO₄ + MnS is exothermic in nature as -27.2 kJ/mole heat is released.

Is H₂SO₄ and MnS a redox reaction

H₂SO₄ + MnS is not a redox reaction as oxidation states are the same for the atoms H, S, O, and Mn before and after the reaction.

Is H₂SO₄ and MnS a precipitation reaction

H₂SO₄ + MnS is not a precipitation reaction as the product MnSO₄  is a water-soluble compound, and the other product is a gas.

Is H₂SO₄ and MnS reversible or irreversible reaction

H₂SO₄ + MnS is an irreversible reaction as it is a unidirectional reaction.

Is H₂SO₄ and MnS displacement reaction

H₂SO₄ + MnS is a displacement reaction as SO₄^2- and S^2- ions are interchanged between two reactant molecules, H₂SO₄ and MnS.

Conclusion

In conclusion, the product MnSO₄ can form a variety of hydrates, all of which can dissolve in water producing a faint pink-colored solution. The other product, H₂S, is a colorless, pungent-odoured gas.
