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.

Question

G.264.

Lead thiocyanate. Pb(SCN), has a Kp value of
2.00 x 10-
AB(s) A+ (aq) +B (aq)
Le Châteller's principle tells us that an increase in either [A] or [B] will shift this equilibrium to the left, reducing the
solubility of AB. In other words, AB is more soluble in pure water than in a solution that already contains A or Bions
This is an example of the common-ion effect
Part B
The common-ion effect can be applied to a solution of lead thiocyanate when potassium thiocyanate is added. Since there
is a common ion, the cyanate ion, the molar solubility of lead thiocyanate goes down in the presence of potassium
thiocyanate.
Calculate the molar solubility of lead thiocyanate in 0.800 M KSCN.
Express your answer with the appropriate units.
