Question

6) Iron (III)chloride + Ammonium hydroxide → Ammonium chloride +
Iron(III)hydroxide

Answer 1

Here is a chemical equation :

FeCl3 + NH4OH = Fe(OH)3 + NH4Cl

Hope it helps.... ❣️

Answer 2

Required chemical equation:-

$FeCl_3 + NH_4OH \longrightarrow NH_4Cl + Fe(OH)_3$.

It is a skeletal equation and it may or may not follow the law of conservation of mass.

More:-

We can balance it.

METHOD 01:- (HIT AND TRIAL)

By observing, (see attach. 01)

we can start balancing with OH ion.

• We multiply 3 with NH4OH to make OH- in LHS = OH- in RHS.

• But NH4 ion in LHS becomes not equal to RHS.
• Thus we again multiply NH4Cl compound with 3 to make NH4+ in LHS = NH4 in RHS.

$\boxed{ FeCl_3 + 3NH_4OH \longrightarrow 3NH_4Cl + Fe(OH)_3 }$.

• Automatically, Cl in RHS become equal to Cl in LHS.

Thus, it is balanced.

METHOD 02:- (Principle Of Applied Chemistry method)

Let us assume that the stoichiometric coefficient of FeCl3, NH4OH, NH4Cl, and Fe(OH)3 as a, b, c, and d respectively.

Then, a = d {Fe}

b = c {NH4}

3a = c {Cl}

If, a = 1,

then,

• d = 1,
• c = 3
• b = 3.

So,

$\boxed{ FeCl_3 + 3NH_4OH \longrightarrow 3NH_4Cl + Fe(OH)_3 }$

is the answer we need.

Note: A balanced equation is also known as a stoichiometric equation. And, this is an example of double displacement reaction (metathesis).
