This reaction can be represented by the following equation: H₃PO₄ + OH⁻ → H₂PO₄⁻ + H₂O
What is buffer solution?Buffer solution resists the changes in pH when small amounts of acid/ base are added.
In the case of buffer made from H₃PO₄ and NaH₂PO₄, the H₃PO₄ will act as weak acid, and NaH₂PO₄ will act as its conjugate base.
When base is added to this buffer solution, it will react with weak acid (H₃PO₄) to form its conjugate base (H₂PO₄⁻ ) and water (H₂O). The H₂PO₄⁻ ion will then act as weak acid and react with any additional base added to buffer. This reaction can be represented by the following equation: H₃PO₄ + OH⁻ → H₂PO₄⁻ + H₂O
OH⁻ represents any hydroxide ion that may be added to the buffer solution.
