Does the temperature affects the pH value/strength of an acid?
I am doing a Science project and I need help on this. Pls pls pls provide as much information as you can. This project is really important as it is added to my final marks.
Pls simplify your answers simpler. I'm studying in a secondary school and I can only understand simple chemical equations like molecules. Pls do not give me hard and difficult equations used in ions. I appreciate that. Thanks for the effort. Try to put ur answer as simple as you can.

increasing temp. very well effects the pH of a substance.
you know pH is defined as -log[H(+)]. so anything which can bring about a change in H^+ concentration will have an effect on pH.
consider the simple example to calculate the pH of water. H2O dissociates to form H(+)ions and OH(-) ions. this process is endothermic so if we increase the temp. the equilibrium
H2O <=> H(+) + OH(-)
will shift in the forward direction resulting in production of more H(+) ions. this will decrease the pH because pH is "minus" of hydrogen ion concentration
good luck for your final marks

sure, temperature does impact the p3557e091623e2d4ecc0ec70b58c7d76 of ideas. p3557e091623e2d4ecc0ec70b58c7d76 is -log[3557e091623e2d4ecc0ec70b58c7d763557e091623e2d4ecc0ec70b58c7d763557e091623e2d4ecc0ec70b58c7d763557e091623e2d4ecc0ec70b58c7d76] and so something that is affecting the concentration of hydrogen ions interior the answer will impact the p3557e091623e2d4ecc0ec70b58c7d76. the least complicated occasion to look at is organic water which has a p3557e091623e2d4ecc0ec70b58c7d76 of seven at 25 Celsius, a p3557e091623e2d4ecc0ec70b58c7d76 of roughly 6.6 at 50 Celsius and a p3557e091623e2d4ecc0ec70b58c7d76 of roughly 7.5 at 0 Celsius. it fairly is because of the fact the dissociation of organic water, 3557e091623e2d4ecc0ec70b58c7d762O <=> 3557e091623e2d4ecc0ec70b58c7d763557e091623e2d4ecc0ec70b58c7d763557e091623e2d4ecc0ec70b58c7d763557e091623e2d4ecc0ec70b58c7d76 H(+) O3557e091623e2d4ecc0ec70b58c7d763557e091623e2d4ecc0ec70b58c7d76-H(+) is an endothermic technique so heating it up will develop the dissociation and will develop the hydrogen ion concentration. At 50 C the conc. of 3557e091623e2d4ecc0ec70b58c7d763557e091623e2d4ecc0ec70b58c7d763557e091623e2d4ecc0ec70b58c7d763557e091623e2d4ecc0ec70b58c7d76 is approximately 2.34 x 103557e091623e2d4ecc0ec70b58c7d76-73557e091623e2d4ecc0ec70b58c7d76 while in comparison with a million x 103557e091623e2d4ecc0ec70b58c7d76-73557e091623e2d4ecc0ec70b58c7d76 at 25 C and approximately 0.33 x 103557e091623e2d4ecc0ec70b58c7d76-73557e091623e2d4ecc0ec70b58c7d76 at 0 C.
