Phosphate buffer molarity
WebMETHOD 1. Prepare sodium phosphate dibasic stock (0.5 M) by dissolving 35.5 g of sodium phosphate dibasic in a final volume of 500 mL of H 2 O. Some crystallization will occur when the solution is stored at 4ºC. Warm on a hot plate and stir until the crystals dissolve. 2. WebBuffer capacity refers to the amount of material that may be added to a solution without causing a significant change in ion activity. It is defined as the ratio of acid or base added (in gram-equivalents per liter) to the change in pH (in pH units).
