Buffer solution can be obtained by mixing aqueous solution of — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

We know that an acidic buffer consists of weak acid and its salt with a strong base. Acetic acid is a weak acid and sodium acetate its salt with strong base NaOH. Therefore, it is an acidic buffer. For a buffer to form, it cannot have a strong acid or base. Option (a) has a strong acid HCl Option (c) has a strong base NaOH Option (d) also has a strong base NaOH So, all of these cannot form buffer.
