Question

Identify $X$ in the following reaction. $FeC{l_3} + 3NaOH$ gives $X + 3NaCl$ .

Answer 1

Hint: We have to know that, the double displacement reaction, might be characterized as the substance responses where one part each of both the responding particles is traded to frame the items. During this response, the cations and anions of two distinct mixtures switch places, framing two altogether various mixtures.


Complete answer:
We have to know that, ferric chloride reacts with sodium hydroxide to produce ferric hydroxide and sodium chloride. The balanced chemical equation is given below,
$FeC{l_3} + 3NaOH \to Fe{\left( {OH} \right)_3} + 3NaCl$
Aqueous ferric chloride $FeC{l_3}$ responds with fluid sodium hydroxide $\left( {NaOH} \right)$ to create ferric hydroxide $\left( {Fe{{\left( {OH} \right)}_3}} \right)$ and sodium chloride $\left( {NaCl} \right)$ . Thus, the yellow-earthy colored shading arrangement will transform into an earthy colored shading hasten. At the point when we add fluid $\left( {NaOH} \right)$ answer for the watery $FeC{l_3}$ arrangement, the earthy colored shading hasten is framed. This encourages ferric hydroxide $\left( {Fe{{\left( {OH} \right)}_3}} \right)$ . Ferric chloride (Iron(III) chloride) is a solvent inorganic compound in water and structures a yellow-earth colored arrangement. Sodium hydroxide is a solid antacid dismal arrangement and promptly gives hydroxyl particles $\left( {OH - } \right)$ .

Additional information:
Anhydrous ferric hydroxide happens in nature as the really uncommon mineral bernalite. Iron oxy-hydroxides are significantly more typical and happen normally as primarily various minerals. Goethite and lepidocrocite, both solidifying in an orthorhombic framework, are the most widely recognized types of iron(III) oxy-hydroxide and the main mineral transporters of iron in soils.
Iron(III) oxy-hydroxide is the primary part of different minerals and mineraloids:
Limonite is a normally happening combination of for the most part goethite, lepidocrocite, quartz and dirt minerals. Ferrihydrite is a shapeless or nanocrystalline hydrated mineral.

Note:
We need to know that the limonite, a combination of different hydrates and polymorphs of ferric oxyhydroxide, is one of the three significant iron metals, having been utilized since in any event 2500 BC. Yellow iron oxide, or pigment yellow, is food and drug Administration supported for use in makeup and is utilized in some tattoo ink.
