What is the effect of temperature on pH?

Solution

We know that ionic product of water (K_w.) increases with the rise of temperature. Therefore, the concentration of H₃O⁺ ions increases with temperature.
$pH space equals space log space fraction numerator 1 over denominator open square brackets straight H subscript 3 straight O to the power of plus close square brackets end fraction$
Therefore, pH value is inversely proportional to $straight H subscript 3 straight O to the power of plus$ ion concentration
Hence pH value decreases with the rise in temperature.
