In the reaction NaOH ---> Na+ + OH-, Na+ is considered a conjugate acid. Though it is very weak but just assuming it could, how could Na+ be/act as an acid if it cannot give off and H+ ions and make a solution acidic.
Homework Answers
NaOH ---> Na+ + OH–
Here Na+ is conjugate acid and OH– is base.
If you want to understand how Na+ can be/act as an acid, lets watch the reaction again: the Na+ release can now react with water
Na+ + H2O ---> NaOH + H+
Here you can see the release of H+ ions. Thus Na+ can act as an acid and it can make a solution acidic.

To understand how buffers use reserves of conjugate acid and conjugate base to counteract the effects of acid or base addition on pH. A buffer is a mixture of a conjugate acid-base pair. In other words, it is a solution that contains a weak acid and its conjugate base, or a weak base and its conjugate acid. For example, an acetic acid buffer consists of acetic acid, CH3COOH, and its conjugate base, the acetate ion CH3COO−. Because ions cannot simply...
