In aqueous solution, classify these compounds as strong acids, weak acids, strong bases, weak bases, or other.
Based on different theories of acid and base, they are defined in terms of proton and electron pairs.
According to the Bronsted-Lowry theory, acids and bases are defined in terms of protons , a hydrogen ion.
By analyzing the value of an acid and base it can be differentiated into strong or weak.
Acid: A molecule that can donate a proton or accept a pair of electrons.
Base: A molecule that can accept a proton or donate a pair of electrons.
The behavior of a strong/weak acid/base in a solution:
A strong acid is one which can donate its proton to a water molecule to form a 100% hydronium ion easily, when dissolved in water.
That is, a strong acid dissolve completely in water to give a hydronium ion.
A weak acid is one which donates its proton to a water molecule to form a hydronium ion slowly when dissolved in water.
That is, a weak acid ionizes partially in water to give hydronium ion.
A strong base is one which can accept a proton from a water molecule to form a 100% hydroxide ion easily when dissolved in water.
That is, a strong base ionizes completely in water to give hydroxide ion.
Weak base is one which accepts a proton from a water molecule to form a hydroxide ion slowly when dissolved in water.
That is, a weak base ionizes partially in water to give hydroxide ion.
The nature of an acid and base whether it is a strong or weak acid or base can be determined using the (dissociation constant) value of the acid and base.
The acid dissociation constant is and the base dissociation constant is. In both cases, the smaller the and value, the stronger the acid and base.
value less than 1 indicates a strong acid.
value greater than 1 indicates a weak acid.
value less than 1 indicates a strong base.
value greater than 1 indicates a weak base.
