HCl is a strong acid with a very high pH, and NaHSO3 is an acid salt. Let us examine this reaction in a bit more detail in this article.
The preparation of HCl is done by dissolving gaseous HCl in water. HCl is colorless with a very strong odor. NaHSO3 is an acidic salt, and when the ionization of acidic salt takes place, H+ ions are yielded.
With the help of various aspects, such as balancing and intermolecular forces, we will discuss this reaction.

- Conjugate pair of NaHSO3 is HSO3-.
HCl and NaHSO3 intermolecular forces
HCl and NaHSO3 have the following intermolecular forces:
- HCl contains two intermolecular forces between its particles: Dipole-Dipole interaction and London dispersion force.
- NaHSO3 has hydrogen bonding, covalent bonding and coordinated intermolecular forces between its particles.
HCl + NaHSO3 reaction enthalpy
The reaction enthalpy of HCl is −92.3 kJ/mol, whereas, for NaHSO3, the reaction enthalpy is -1387.1 kJ/mol.
Is HCl+ NaHSO3 a buffer solution
HCL + NaHSO3 is not a buffer solution because HCl is a strong acid and a buffer solution can not contain a strong acid as it will ionize completely.
Is HCL + NaHSO3 a complete reaction a complete reaction
HCL + NaHSO3 is a complete reaction because two reactants combine to form three products, among which one is soluble in water.
Is HCl + NAHSO3 an exothermic or endothermic reaction
The reaction between HCl and NaHSO3 is exothermic as a lot of heat is evolved during the reaction, and the reaction enthalpy is also positive.
Is HCL + NaHSO3 a redox reaction
The reaction of HCl with NaHSO3 is a redox reaction because oxidation state changes from reactant to product side.
Is HCL + NaHSO3 a precipitation reaction
The reaction between HCl and NaHSO3 is not a precipitation reaction because the product formed is NaCl (common salt) which is completely soluble in water.
Is HCL + NaHSO3 reversible or irreversible reaction
The reaction between HCl and NaHSO3 is irreversible because the salt produced is completely soluble in water. Hence the reaction can not go back to the reactant phase.
Is HCl +NaHSO3 displacement reaction
The reaction between HCl and NaHSO3 is a double displacement reaction because the two reacting molecules exchange their corresponding ions.
This reaction yielded three products, among which NaCl is known as rock salt and has a ph 7. NaCl is commonly used as a food preservative and also helps to enhance the flavour of the food. It is also used to melt ice in low temperature countries, whereas SO2 is a colourless gas that helps manufacture sulphuric acid.
