WebSep 7, 2024 · How Temperature Affects pH Pure water under standard conditions (25°C and 1 atm) is 7 pH. At 30°C, the pH drops to 6.92. This is not an error. Water dissociates into ions more at higher temperatures, leading to a higher concentration of hydrogen ions (or H 3 O + ). WebTemperature Depending on the buffer substance, its pH may vary with temperature. It is therefore advisable, as far as possible, to set the pH at the working temperature to be used for the investigation. For instance the physiological pH value for most mammalian cells at 37°C is between 7.0 and 7.5. The temperature dependence of a buffer system
