Webthe nature of the buffer (–0.028 pH/°C for Tris and –0.0028 pH/°C for phosphate). For this rea-son, temperature is usually reported along with pH values. The pH of water itself varies with temperature: 7.27 at 10 °C, 7.00 at 25 °C, and 6.63 at 50 °C. 2. Buffer capacity. Buffer capacity is the ability of a buffer to resist changes in pH.
