Could someone please explain what is special about Zn vs. Fe (and what other elements would behave like Zn or Fe)?
The question:
Ten mL of a 1 M NaOH solution is added to equal volumes of two saturated solutions. One solution contains an excess of Zn(OH)2(s) and the other an excess of Fe(OH)2(s). Why does more Zn(OH)2 dissolve in the first flask, but more Fe(OH)2 precipitate in the second flask?
Ksp of Zn(OH)2: 1.8 x 10^-14
Ksp of Fe(OH)2: 1.1 x 10^-14
A) The Ksp of...
Solubility wrt adding NaOH to Zn(OH)2 vs Fe(OH)2
