Question

when a small amount of naoh is added to phosphate buffer solution it will react with? ​

Answer 1

$\huge{\purple{\boxed{\red{\boxed{\mathfrak{Answer}}}}}}$

When a strong base (OH-) is added to a buffer solution, the hydroxide ions are consumed by the weak acid forming water and the weaker conjugate base of the acid. The amount of the weak acid decreases while the amount of the conjugate base increases.

Answer 2

Explanation:

normal sodium phosphate buffer recipe is to mix a appropriate amount of salt (NA2HPO4) and weak acid (NAH2PO4). my question is if i take any of these chemicals and set pH to desired pH i.e. 7.4 would it work as a buffer?
