Buffer Solution, pH 4.00, Coded Pink

A buffer solution has the capability to resist change in its pH upon the addition of acid or base in a small quantity. It possesses a working range of pH values and capacity that dictates its stability before any change and the amount by which it will change. It usually consists of a weak conjugate acid-base pair. This pair might contain a weak acid and its conjugate base, or a weak base and its conjugate acid. The choice of the pair is simply dependent upon the desired pH when preparing the buffer solution. Lab Alley’s Buffer Solution, pH 4.00, Coded Pink is a combination of 1,2-Benzenedicarboxylic acid, monopotassium salt (1.0 wt.%), Formaldehyde(0.05 wt.%), Methyl alcohol (0.02 wt.%), and purified Water.
