Ph is affected by temperature

WebbWhen the pH drops below pH 8.3 phenolphthalein goes colourless. Here, an alkaline solution of milk, lipase and phenolphthalein will change from pink to colourless as the fat in milk is broken down to form fatty acids (and glycerol) thus reducing the pH to below 8.3. The time taken for this reaction to occur is affected by temperature. WebbAn increase in the temperature promotes the decomposition as well as a higher pH value. For optimum stability, the pH range of pure H 2 O 2 is below 4.5. Above pH 5, the decomposition increases sharply. Therefore, commercial solutions are generally adjusted to a pH value below 5.
