Question

Explain why a solution of FeSo4 is acidic

Answer 1

Answer:

Explanation:

FeSO4 is acidic in nature because it is formed by the reaction of strong acid sulphuric acid(H2SO4) and weak base ferrous oxide(Fe(OH)2). And results the formation of acidic salt ferrous sulphate (FeSO4).

Answer 2

The solution of FeSo4 is acidic.

• FeSO₄ dissolution in water produces more H+ which is acidic (<pH 6).
• FeSO₄ is known as ferrous sulphate and it is formed by a chemical reaction between sulfuric acid (strong acid) and ferric hydroxide (a weak base).
• FeSO₄ is a salt that is made up of very strong acid and a weak base.
• The reaction equation will be as follows.

            H₂SO₄ + Fe(OH)₂ → FeSO₄ + 2H₂O

• It is known that a reaction between a strong acid and a weak base will always result in the formation of acidic salt.
• Therefore, a solution of FeSO₄ is acidic in nature.
