About Buffer Solution, pH 7.0, Coded Yellow

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 desiredpH when preparing the buffer solution. Lab Alley’s Buffer Solution, pH 7.0, Coded Yellow is a combination of Dihydrogen Potassium Phosphate (0.7 wt.%), Sodium Hydroxide (0.1 wt.%), FD&C Yellow No. 5 (0.0-0.02 wt.%), and purified Water (balanced). It is color-coded yellow for easy identification and appears as an opaque liquid at ambient conditions. In the United States of America (USA), Lab Alley is selling its high-quality Buffer Solution, pH 7.0, Coded Yellow online at laballey.com.
