How to balance HCl + Li3PO4?

  • The HCl + Li3PO4 chemical equation gets balanced using the following steps.
  • The unbalanced reaction equation is:
  • HCl + Li3PO4 → LiCl + H3PO4
  • To balance both sides first multiply HCl by three on the reactant side we get.
  • 3 HCl + Li3PO4 → LiCl + H3PO4
  • Later multiplying LiCl with three on the product side we get the complete balanced equation as follows.
  • 3HCl + Li3PO4 → 3LiCl + H3PO4

HCl + Li3PO4 net ionic equation.

  • The net ionic equation of HCl + Li3PO4 chemical reaction is given below:
  • Li3PO4(s) + 3H+(aq) + 3Cl(aq) = 3Li+(aq) + 3Cl(aq) + 3H+(aq) + PO43-(aq)

HCl + Li3PO4 conjugate pairs.

HCl and Li3PO4 are conjugate pairs. HCl is a strong acid and dissociates as H+ and Cl- ions. As the HCl donates its protons, Cl- acts as a conjugate base and the H+ ion act as conjugate acid. Thus, LiCl is the conjugate base and H3PO4 is the conjugate acid.

HCl and Li3PO4 intermolecular forces.

  • The intermolecular force of attraction between HCl and Li3PO4 is:
  • HCl = dipole-dipole intermolecular force.
  • Li3PO4 = ion-dipole intermolecular force.

HCl + Li3PO4 reaction enthalpy.

  • The reaction enthalpy of HCL + Li3PO4 is – 1880.9 kJ/mol.
  • HCl = enthalpy of formation of HCl is −92.3 kJ/mol.
  • Li3PO4 = enthalpy of formation of Li3PO4 is 298.15 K, kJ/mol.
  • LiCl = enthalpy of formation of LiCl is -409 kJ/mol
  • H3PO4 = enthalpy of formation of H3PO4 is -1265.7 kJ/mol
  • Reaction enthalpy of HCl + Li3PO4 is = enthalpy of product – enthalpy of reactant
  • Reaction enthalpy of HCl + Li3PO4 is = – 1674.7 – (206.2) = – 1880.9 kJ/mol

Is HCl + Li3PO4 a buffer solution?

HCl + Li3PO4 can form a buffer solution. As in the HCl, it contains HCl which is a strong acid and Li3PO4 is a basic salt that has a pH value of more than 7 that can form a buffer solution.

Is HCl + Li3PO4 a complete reaction?

HCl + Li3PO4 is not a complete reaction as it is not a reversible reaction and not achieving equilibrium. The reaction is a complete reaction only if achieves equilibrium.

Is HCl + Li3PO4 an exothermic or endothermic reaction?

HCl is a strong acid shows an exothermic reaction and Li3PO4 is a basic salt shows an endothermic reaction. If Li3PO4 salt dissolve in water or other substance shows an endothermic reaction.

Is HCl + Li3PO4 a precipitation reaction?

HCl + Li3PO4 is a precipitate reaction. When HCl reacts with Li3PO4 forms a precipitate of LiCl salt and H3PO4 acid.

Is HCl + Li3PO4 reversible or irreversible reaction?

HCl + Li3PO4 is an irreversible reaction and not a reversible reaction, as this reaction is not a redox reaction and cannot acquire equilibrium.

Is HCl + Li3PO4 displacement reaction?

HCl + Li3PO4 is not a displacement reaction as no atoms of the reaction displaced other atoms because it is a double displacement reaction. In this reaction, there is the exchange of atoms occurs causing a double displacement reaction.

Conclusion:

HCl + Li3PO4 is a reaction that occurs between a strong acid and a basic salt. It is a double displacement reaction and shows a balanced equation 3HCl + Li3PO4 → 3LiCl + H3PO4. The product of this reaction is LiCl and H3PO4. It is an endothermic reaction.
