## HCl + Fe(OH)3 titration

Titration is take place between the solution of HCl and Fe(OH)3 in a specific amount. This titration reveals that 35.94 ml of HCL Solution is sufficient lớn neutralise 18.62 ml of Fe(OH)3 Solution. The process of titration is as follows:

### Titrant and titre

Here the titrant is HCL and titre is Fe(OH)3.

### Indicator

The indicator used in the titration of this kind of acid-base solution is Na2CO3.10H2O.

### Procedure

HCl is taken in the burette by taking it through a pipette. The Fe(OH)3 solution is taken the conical flask and placed below the burette. Now, HCl is added in Fe(OH)3 drop wise and the Fe(OH)3 solution starts changing color from colorless lớn reddish brown at a certain point which is taken for calculation.

## HCl + Fe(OH)3 net ionic equation

## HCl and Fe(OH)3 intermolecular forces

Intermolecular force between H and Cl in HCl is as weak as intermolecular force between Fe and OHion. This is why HCl leaves proton (H+) easily and Cl ion creates a bond with Fe getting a stronger intermolecular attraction force.

## HCl + Fe(OH)3 reaction enthalpy

Enthalpy of the reaction is calculated as nearer lớn 2221 KJ/mol by following the formula: Enthalpy = (bond energy of H-Cl) – (lattice energy of Fe(OH)2)

• Bond energy of H-Cl = 432 KJ/mol
• Bond energy of Fe(OH)3 = 2653 KJ/mol
• Enthalpy of the reaction HCl + Fe(OH)2 = (432 – 2653) = – 2221 KJ/mol

## Is HCl + Fe(OH)3 a buffer solution?

HCl + Fe(OH)3 is not a buffer solution as Fe(OH)3 is not the conjugate base of HCl. They bởi not pair with each other lớn make a neutral compound as product.

## Is HCl + Fe(OH)3 a complete reaction?

HCl + Fe(OH)3 is a complete reaction as it produces reliable and expected products by neutralizing each other.

## Is HCl + Fe(OH)3 an exothermic or endothermic reaction?

HCl + Fe(OH)3 is an Exothermic reaction as the enthalpy of the reaction is negative which means the reaction gives out heat energy instead of taking it from outer surroundings.

## Is HCl + Fe(OH)3 a redox reaction?

HCl + Fe(OH)3 can be considered a redox reaction as HCl leaves proton (H+) which refers lớn oxidation and Ferric hydroxide leaves OH- ion which refers lớn a reduction reaction. Both happen together in one single reaction therefore, it might be a redox reaction.

## Is HCl + Fe(OH)3 a precipitation reaction?

HCl + Fe(OH)3 can be called as a precipitation reaction where the precipitation of Ferric chloride is found lớn dominate the overall reaction actively. A reddish-brown colour precipitation is found lớn take place in the product solution.

## Is HCl + Fe(OH)3 reversible or irreversible reaction?

HCl + Fe(OH)3 is clearly an irreversible reaction where the products ferric chloride and water molecules bởi not react with each other lớn produce the reactant Hydrochloric acid and Ferric hydroxide again. No backward reaction refers it as an irreversible reaction.

## Is HCl + Fe(OH)3 displacement reaction?

HCl + Fe(OH)3 might be called a double displacement reaction as hydroxyl ions from Ferric hydroxide gets a displacement lớn HCl by removing Cl ions from Hydrochloric acid. That reduced Cl ions get addition with iron remaining after leaving OH ions.

#### Conclusion

This article has successfully found the unique reaction between Hydrochloric acid and Ferric hydroxide. This reaction follows the general rule of acid base reaction where they gives out metal chloride and water molecules.
