13 Facts on HCl + Li3P: What, How To Balance & FAQs


The chemical names of HCl and Li3P are hydrochloric acid and lithium phosphide. Let us discuss how to balance the HCl + Li3P chemical reaction below.

Hydrochloric acid (HCl) is composed of one hydrogen atom and one chlorine atom. HCl is a strong acid. Lithium phosphide (Li3P) is composed of three lithium metals and one phosphorous atom. Li3P is an inorganic salt compound. Li3P can form by heating lithium metal with phosphorous.

In this article, we are discussing titration, reaction type, product, buffer solution, how to balance, and various other facts and FAQs on HCl + Li3P chemical reaction.

What is the product of HCl and Li3P?

The product of the HCl and Li3P reaction is Lithium chloride (LiCl) and phosphine gas (PH3). When hydrochloric acid and lithium phosphide get reacts with each other they form LiCl and PH3 as a product. The reaction equation is given below.

3HCl + Li3P → 3LiCl + PH3.

What type of reaction is HCl + Li3P?

The HCl and Li3P undergo a Double displacement reaction also known as a salt metathesis reaction.

How to balance HCl + Li3P?

The HCl + Li3P chemical equation gets balanced using the following steps.

  • The unbalanced reaction equation is:
  • HCl + Li3P  LiCl + PH3
  • To balance both sides first multiply HCl by three on the reactant side we get.
  • 3HCl + Li3P → LiCl + PH3
  • Later multiplying LiCl with three on the product side we get the complete balanced equation as follows.
  • 3HCl + Li3P → 3LiCl + PH3

HCl + Li3P net ionic equation.

  • The net ionic equation of the HCl + Li3P chemical reaction is given below:
  • 3H+ + 3Cl + Li3P → 3Li+ + 3Cl + PH3
  • By removing the common elements from both sides we get.
  • 3H+ + Li3P → 3Li+ + PH3
  • Above is the net ionic equation of the HCl + Li3P chemical reaction.

HCl + Li3P conjugate pairs

HCl and Li3P 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.

HCl and Li3P intermolecular forces

HCl acid has a dipole-dipole intermolecular force. As HCl is a polar compound. The H atom and Cl atom of HCl have partial positive and negative charges on them. The force of attraction with 2 opposite charge particles causes dipole-dipole force within HCl and Li3P reaction.

Is HCl + Li3P a buffer solution?

HCl + Li3P is not a buffer solution. As HCl is a strong acid and Li3P is an inorganic salt that cannot form a buffer solution and cannot maintains the pH level of other solutions.

Is HCl + Li3P a complete reaction?

HCl + Li3P 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 + Li3P an exothermic or endothermic reaction?

HCl + Li3P is an endothermic reaction. Basically, HCl is an acid and shows an exothermic reaction and Li3P is a salt and shows an endothermic reaction. When HCl is added to Li3P, the heat gets absorbed by Li3P and shows an endothermic reaction.

Is HCl + Li3P a redox reaction?

HCl + Li3P is not a redox reaction because it is a double displacement reaction. There is no transfer of electrons within HCl + Li3P. Also, there is no change in the oxidation state of any element of HCl + Li3P, thus it is not redox.

Is HCl + Li3P a precipitation reaction?

HCl + Li3P is a precipitation reaction as there is the formation of the solid product i.e. LiCl. When HCl reacts with Li3P it forms a precipitate of LiCl. As Li3P is an alkali metal salt that does not dissolve in HCl acid.

Is HCl + Li3P reversible or irreversible reaction?

HCl + Li3P is an irreversible reaction and not a reversible reaction. This reaction is not a redox reaction and cannot acquire equilibrium. Thus it is not a reversible reaction.

Is HCl + Li3P displacement reaction?

HCl + Li3P is not a displacement reaction because it is a double displacement reaction. None of the atoms of the reaction displaced another atom and hence it is not a displacement reaction.

Conclusion:

HCl + Li3P is a reaction that occurs between a strong acid and an alkali metal salt. It is a double displacement reaction and shows a balanced equation 3HCl + Li3P → 3LiCl + PH3. The product of this reaction is lithium chloride and phosphine gas. It is an endothermic reaction.
