Which mechanism causes elevated acidity when dissolved ferrous sulfate interacts?

💡 Explanation

Hydrolysis of solvated iron releases protons, reducing pH, because water molecules coordinate with the Fe2+ ion. Therefore acidity increases, rather than remaining neutral, because oxygen reduction or sulfate reactions influence concentration slightly.
