Interpretation : The magnesium hydroxide and calcium hydroxide are classified as strong bases even though their saturated solutions are only mild basic are to be explained.
Concept Introduction : Bases are substances that ionize in aqueous solutions to produce hydroxide ions
Answer to Problem 68A
Magnesium hydroxide and calcium hydroxide are classified as strong bases because they dissociate completely in water and have a high base dissociation constant.
Explanation of Solution
Based on the amount they ionize in water, acids and bases are categorized as strong or weak.
In an aqueous solution, a strong base completely dissociates into metal ions and hydroxide ions.
Magnesium hydroxide and calcium hydroxides are strong bases.
These compounds are not easily soluble in water due to the presence of divalent positive charges.
Certain amounts of these compounds dissociate completely in water.
The base dissociation constant of these compounds is high.
