When we have:
Zn(OH)2 → Zn2+ 2OH- with Ksp = 3 x 10 ^-16
and:
Zn2+ + 4OH- → Zn(OH)4 2- with Kf = 2 x 10^15
by mixing those equations together:
Zn(OH)2 + 2OH- → Zn(OH)4 2- with K = Kf *Ksp = 3 x 10^-16 * 2x10^15 =0.6
by using ICE table:
Zn(OH)2 + 2OH- → Zn(OH)4 2-
initial 2m 0
change -2X +X
Equ 2-2X X
when we assume that the solubility is X
and when K = [Zn(OH)4 2-] / [OH-]^2
0.6 = X / (2-2X)^2 by solving this equation for X
∴ X = 0.53 m
∴ the solubility of Zn(OH)2 = 0.53 M
Answer:
Explanation:
The process of gaining or losing electrons from a neutral atom or molecule is called ionization. Atoms can be ionized by bombardment with radiation, but the more purely chemical process of ionization is the transfer of electrons between atoms or molecules
Answer:
A formula unit indicates the lowest whole number ratio of ions in an ionic compound. Because the positively and negatively charged ions in an ionic compound are arranged in a crystal lattice, there is no discrete particle comparable to a molecule.
Explanation:
The answer is going to be hydrochloric acid, therefore hydrochloric acid is a binary acid.
On a chilly, humid evening, intermolecular forces enable fog to form. The gaseous water molecules condense as a result of powerful molecular interactions.
What force allows fog formation?
From the south, warm, moist air is brought in, and if there is snow or cool precipitation on the ground, it will come into touch with the warm, moist breezes. The air coming in will cool as a result of this air-ground contact. Dew point rises at that position, leading to high humidity and the formation of fog.
What is molecular interactions?
Interactions between molecules or between atoms without bonds are referred to as molecular interactions. There are three types of molecular interactions: cohesive (attraction between like), adhesive (attraction between unlike), and repulsive forces.
