Hydrogen bromide (HBr) and Potassium oxide (K2O) are highly reactive ionic compounds. Let’s take a deep dive to learn about the reaction of HBr and K2O in detail.
HBr is a hydrogen halide, a colourless gas that dissolves and is soluble in water. The aqueous solution of HBr is used in laboratories as a reagent. K2O has a basic character with a characteristic pale-yellow colour.
In this article, we will discuss the numerous features of the HBr + K2O reaction in detail.
What is the product of HBr and K2O?
HBr and K2O react to produce potassium bromide (KBr) and water (H2O).
2HBr + K2O → 2KBr + H2O
What type of reaction is HBr and K2O?
HBr and K2O reaction can be classified as neutralisation reaction.
How to balance HBr + K2O
The general equation of the HBr + K2O reaction can be written as:
HBr + K2O → KBr + H2O
- A balanced reaction has equal moles on the reactant and the product side.
- The above reaction can be balanced by adding 2 moles of HBr on the reactant side and 2 moles of KBr on the product side.
- The balanced reaction can be given by:
- 2HBr + K2O → 2KBr + H2O
HBr + K2O titration
The direct titration of the HBr and K2O mixture is not possible because we can’t achieve the end point directly.
HBr + K2O net ionic equation
HBr + K2O is a neutralisation reaction the net ionic reaction can be given by:
H+(aq) + OH–(aq) → H2O(l)
HBr + K2O conjugate pairs
The conjugate pairs of the HBr + K2O reaction are as follows:
- The Conjugate base of HBr (Acid) is KBr.
- The Conjugate acid of K2O (Base) is H2O.
HBr and K2O intermolecular forces
The intermolecular forces in HBr and K2O are as follows:
- HBr has dipole-dipole intermolecular forces.
- The forces that hold K2O are ion-dipole interactions.
Is HBr + K2O a buffer solution
HBr + K2O don’t form a buffer solution because HBr is a strong acid, and buffers need a weak acid and its conjugate base to keep the pH constant.
Is HBr + K2O a complete reaction
The reaction between HBr and K2O is complete as the reactants formed don’t react further.
Is HBr + K2O an exothermic or endothermic reaction
HBr + K2O is an exothermic reaction in which the heat generated is utilised to carry out the reaction.
Is HBr + K2O a redox reaction
The reaction between HBr + K2O is not a redox reaction, as the oxidation state of the species remains the same.
Is HBr + K2O a precipitation reaction
HBr + K2O can’t be classified as a precipitation reaction because the products formed are soluble and don’t lead to forming a precipitate.
Is HBr + K2O reversible or irreversible reaction
HBr + K2O is an irreversible reaction as the products formed don’t react further.
Is HBr + K2O displacement reaction
HBr + K2O can be classified as a double displacement reaction as cation and anion swap their position, leading to new products formation.
Conclusion
In a nutshell, HBr + K2O reaction can be categorised as neutralisation and double displacement reaction. The reaction has negative enthalpy and is therefore exothermic. The reaction under observation has high synthetic application.
