H2SO4 and Na2HPO4 reaction enthalpy
H2SO4 and Na2HPO4 reaction is exothermic, subsequent in a reduction in enthalpy.
H2SO4 and Na2HPO4 a buffer solution
H2SO4 and Na2HPO4 reaction mixture cannot act as a buffer solution as Na2HPO4 is a weak acid, not a conjugate base of H2SO4, which is a strong acid.
H2SO4 and Na2HPO4 a complete reaction
H2SO4 and Na2HPO4 reaction is complete. Here, the reactant’s components combine to create a defined product.
Is H2SO4 and Na2HPO4 an exothermic or endothermic reaction
H2SO4 and Na2HPO4 reaction in an exothermic process.
- Let’s calculate the energy of the reaction using below mentioned method:
- First, establish a reaction
- Na2HPO4 + H2SO4 = NaHSO4 + H3PO4
- Then mention the energy of individual elements.
Element | Energy in kJ/mol for element |
Na2HPO4 | -3516.5 |
H2SO4 | -814 |
NaHSO4 | -1387.1 |
H3PO4 | -1265.7 |
- Reactant = -3516.5 kJ/mol + -814 kJ/mol = 4330
- Product = -1387.1 kJ/mol + -1265.7 kJ (g) = 2652.1
- Enthalpy= Product – reactant = -1677.9
- The reaction energy is negative, so it causes energy to be released, resulting in an exothermic reaction.
Is H2SO4 and Na2HPO4 a redox reaction
H2SO4 and Na2HPO4 is not redox reaction. The formulas reveal that there is no net change in it.
+1 +1 +5 -2 +1 +6 -2 +1 +1 +6 -2 +1 +5 -2
Na2 H P O4 + H2 S O4 = Na H S O4 + H3 P O4
Is H2SO4 and Na2HPO4 a precipitation reaction
H2SO4 and Na2HPO4 reaction is not a precipitation reaction because of the formation of the aqueous form of phosphoric acid.
Is H2SO4 and Na2HPO4 reversible or irreversible reaction
H2SO4 and Na2HPO4 is an irreversible reactions. As the formation of H3PO4 and NaHSO4, which are both weak acids. Consequently, the equilibrium cannot be altered in the opposite direction.
Is H2SO4 and Na2HPO4 displacement reaction
H2SO4 and Na2HPO4 reaction is a displacement reaction because one element from each compound was transferred to the other.
Conclusion
In the displacement reaction between the weak acid Na2HPO4 and the H2SO4, sodium hydrogen sulfate and phosphoric acid were produced. This exothermic procedure results in the release of energy, preventing the equilibrium from moving and contributing to irreversibility.
