How you classify the solution as a best buffer solution?

buffer capacity is the amount of acid or base that can be absorbed by a buffer solution without any significant change

DNA is commonly stored in Tris-EDTA buffer, containing 100mM Tris-Cl, 10mM EDTA (pH 8.0),made in nuclease-free distilled water.

GTE stands for Glucose-Tris-EDTA. The Tris is used to buffer whatever you're adding this to at pH 7.9. EDTA binds divalent cations like Ca2+ and Mg2+, thereby weakening the cell envelope of cells in...

buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. It has the property that the pH of the solution changes...

Acetic acid is added to the solution, but the pH of the solution does not change. Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
