Question

At 25 C, all of the following ions produce an acidic solution, except ___.

a-NH₄⁺
b-HSO₃⁻
c-HPO₄ 2⁻
d-[Fe(H₂O)₆]₃⁺
e-[Al(H₂O)₆]₃⁺

Answer 1

NH₄⁺ is the ion that does not produce an acidic solution at 25°C.

Step-by-step explanation:

At 25°C, all of the following ions produce an acidic solution, except NH₄⁺. The other ions listed - HSO₃⁻, HPO₄²⁻, [Fe(H₂O)₆]³⁺, and [Al(H₂O)₆]³⁺ - all act as weak acids in water and, therefore, contribute to the acidity of the solution.
