Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
Can you explain the problem please? And where did the X4 came from?
![The Ksp for LaF3 is 2.0 x 10-19. What is the solubility of LaF in water in moles per liter
(Molar solubility)?
Solution
Again, set up an equilibrium table according to the solubility equilibrium:
La 3+ (aq) + 3F- (aq)
LaF3 (s)
Initial (M)
Eq (M)
0
0
X
3x
Ksp =[La3+] [F-13
=> Ksp = (x)(3x)³
=> 2 × 10-19 = 27x4
2.0 × 10-19
=
x4
(7.4 × 10-21) 1/4 = x
X
27
x = 9.0 × 10-6 M = [La³+] This is the Molar solubility of La 3+
Thus, by 1:1 formula stoichiometry => 9.0 x 106 M = [LaF3]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F637a8243-98d2-45ca-8dd1-4e9d7d0f97ca%2F6124bc16-d65b-4f64-949a-a5e917a5f955%2F30lys2n.jpeg&w=3840&q=75)
