Question

When ferrous ammonium sulphate reacts with sodium hydroxide then what will be the product? ho







​

Answer 1

Answer:FeSO4 (aq) + (NH4)2SO4 (aq) + 4 NaOH (aq) -----> Fe(OH)2 (s) + 2 Na2SO4

Explanation:Most d-block ( in periodic table) metals (Fe, Co, Ni, etc.) form water-insoluble hydroxide salts. Ferrous hydroxide is a reddish, water-insoluble solid, and the above reaction proceeds because the driving force of the reaction is: 1) the removal of Fe(OH)2 from the system (via precipitation), and 2) the formation of products whose basicity are less than that of NaOH (in other words, Fe(OH)2 and NH4OH are much less basic than NaOH). Reactions where the products are either less acidic or basic than the reactant acid or base are usually favorable.
