Question

What do you observe when ammonium hydroxide is added to the aqueous solution of Iron III chloride?

Answer 1

Hint : When different compounds react with each other, the formation of the resultant product is governed by the different types of reaction that exist I.e. Displacement reaction, double-displacement reaction, disproportionation reaction, precipitation reaction etc.

Complete Step By Step Answer:
Let's first understand the compounds and know about their compositions.
Iron III chloride is an inorganic compound that can be found in the form of crystalline solid. In this iron is found in the $+ 3$ state. It is an anhydrous compound.
So, now let’s have a look at the chemical reaction when ammonium hydroxide is added to the aqueous solution of Iron III chloride.
So, the chemical reaction for this equation will be as follows:
$6N{H_4}OH + 2FeC{l_3} \to 2Fe{(OH)_3} + 6N{H_4}Cl$
Hence, when ammonium hydroxide is added to the aqueous solution of Iron III chloride then the ‘red precipitate’ of iron hydroxide is formed and also the ammonium chloride is produced.
The important point here to keep in mind is that, in the above reaction the ‘Red precipitate’ of the iron hydroxide is formed. This is the positive indication for the identification of the reaction, i.e. the above reaction has completed or has taken place.
So, from the above discussion we can say that the answer is crystal clear.

Note :
Ammonium hydroxide is the colourless compound in a liquid chemical solution. It can be produced by dissolving the ammonia in water, then it can form Ammonium hydroxide. It belongs to the class of compounds known as ‘Caustics’.
