# The effect of temperature and ph

The ph value of a solution is directly dependent on the temperature a ph value without a temperature value is incoherent solution temperature compensation (stc) converts measured ph to the ph at 25°c ph values taken at the same temperature or converted using solution temperature compensation can be compared to each other to achieve highest accuracy, calibrate and measure at the same temperature. The effect of temperature on solution ph increases as the ph approaches the dissociation constant for strong acids and bases, the dissociation constants are beyond the 0 to 14 ph range, so the primary effect is the water dissociation constant that is 1 x 10-14 at 25°c. The $k_\mathrm w$ is a function of temperature it is $10^{-14}$ at $25\ \mathrm{^\circ c}$ when the temperature is $50\ \mathrm{^\circ c}$, the $k_\mathrm w$ can be calculated to be somewhere aro.
