We’re asked to classify each compound of the important chemical species present in a water solution based on the type of compound as follows:
[ ionic, molecular, strong acid, weak acid, strong base, weak base. ]
We need to remember 3 important aspects to classify them:
First: Ionic compounds are made between elements of metallic and nonmetallic elements (where H is considered metallic), while molecular compounds are made of nonmetallic elements.
Second: In a solution, an acid donates a proton (H) while a base accepts a proton with the solvent according to the Bronsted-Lowry theory.
Third: If the compound dissociates completely, the acid or base is strong. If the compound dissociates partially, the acid or base is weak.
