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 5.5 is a combination of Potassium Acid Phthalate (1.02 wt.%), Sodium Hydroxide (0.15 wt.%), Proprietary (0.01 wt.%), and purified Water (balanced). It appears as a red-tinted opaque liquid having good solubility in water at ambient conditions. In the United States of America (USA), Lab Alley is selling its high-quality Buffer Solution, pH 5.5 online at laballey.com. Due to its high purity, this Lab Alley product is highly recommended for labs and commercial applications.
