If theres saturated aqueous solution of Fe(OH)2 at 25°C and Ksp = 4.87 × 10−17, which one is false statement?
A. Adding acid to the solution will increase the solubility.
B. Fe(OH)2 is a strong electrolyte.
C. The pH of the solution will be greater than 7.
D. The solubility of the salt will be equal to [OH−].
E. Addition of more solid Fe(OH)2 to the solution will increase the hydroxide ion concentration.
Whats pH of saturated solution of Mg(OH)2? (Ksp is 1.2 *10^-11)
