# How does Borax Solution act as a buffer? [closed]

What type of buffer is it? If it's a Weak Acid-Conjugate Base type of buffer, what is the weak acid and conjugate base?

Borax reacts in hydrochloric acid in the preparation of the buffer to give the boric acid through the following reaction $$\ce{Na2B4O7.5H2O + 2HCl -> 4H3BO3 + 2NaCl + 5H2O}$$
