Discover The 15 Incredible Facts On HCl + BeO Reaction

BeO (beryllium oxide) is a colourless inorganic compound sometimes referred to beryllia. Let us read how it reacts with HCl through this article.

HCl (hydrochloric acid) and BeO react to produce products, namely BeCl2 (beryllium chloride) and H2O (water). BeO has a white-coloured crystal because of its amorphous solid properties. It was historically known for its sweet taste. HCl is an important part of our digestive system having a pungent smell.

HCl + BeO titration Procedure

  • Prepare the titrant (the known substance) by dissolving a known mass of the BeO in a known volume of water.
  • Prepare the titrand (the unknown substance) by measuring 10 mL of the HCl in a conical flask.
  • Note the initial volume of titrant in the burette and add 2-3 drops of methyl orange in a conical flask.
  • Slowly add the titrant to the titrand while stirring continuously.
  • Observe the colour change of the titrand from red to yellow as the titrant is added.
  • Note the final volume of titrant in the burette after the endpoint is reached.
  • Calculate the concentration of the unknown acid using the mass of the BeO, the volume of the HCl and the volume of the BeO added.
  • Repeat the titration until concurrent results are obtained.

HCl + BeO net ionic equation

The HCl + BeO net ionic equation is,

2 H+ (aq.) + BeO (s) = Be2+ (aq.) + H2O (l)

  • The balanced molecular equation for HCl + BeO is,
  • 2 HCl + BeO = BeCl2 + H2O
  • The chemical state of each molecule in the equation is indicated.
  • 2 HCl (aq.) + BeO (aq.) = BeCl2 (aq.) + H2O (l)
  • Strong electrolytes dissociate into their respective ions.
  • 2 H+ (aq.) + 2 Cl (aq.) + BeO (s) = Be2+ (aq.) + 2 Cl (aq.) + H2O (l)
  • Spectator ions should be eliminated as they do not contribute to the process.
  • Thus, the net ionic equation obtained is,
  • 2 H+ (aq.) + BeO (s) = Be2+ (aq.) + H2O (l)

HCl + BeO conjugate pairs

HCl and BeO has the following conjugate pairs.

  • The conjugate pair of HCl contains its conjugate base Cl.
  • Conjugate pair of H2O consists of HCl and its conjugate base OH.

HCl and BeO intermolecular forces

The intermolecular force present in compounds available in HCl + BeO reaction is:

  • BeO contains unsaturated covalent bonds between them.
  • HCl consists of London dispersion and dipole-dipole forces.

HCl + BeO reaction enthalpy

The reaction enthalpy for HCl + BeO is 153.5 kJ/mol. This value can be calculated using the standard enthalpies of formation for given reactants and products.

S. no.MoleculesEnthalpy of formation (in kJ/mol)
1.HCl-167.16
2.BeO-599
3.BeCl2-494
4.H2O-285.83
Enthalpy of formation of compounds

Reaction enthalpy (ΔHf) = Standard enthalpy of formation (products – reactants)

ΔHf = [2*(-167.16) + (-599)] – [(-494) + (-285.83)]

Thus, ΔHf = 153.5 kJ/mol.

Is HCl + BeO a buffer solution

HCl + BeO is not a buffer solution as there must be present a weak acid or base for a solution to act as a buffer but HCl is a strong acid.

Is HCl + BeO a complete reaction

The HCl + BeO reaction is a complete reaction and no other steps are left to proceed on.

Is HCl + BeO an exothermic or endothermic reaction

Conclusion

This article concludes that BeO acts as a base when added to HCl as it is amphoteric. The reaction requires some energy in the form of heat to proceed in the forward direction. The bond between Be and O in BeO is formed by sharing electrons between these atoms, which makes the oxygen complete its octet.
