pH

[705596384]

Does temperature have an impact on the pH levels of bases/acids?

[AnoushkaBhat2J]

pH is inversely proportional to the temperature. When the temperature of a solution rises, more H+ molecules form due to increased molecular vibrations.

[305597516]

I think so, based on the fact that temperature will change K. Since you need K to find the concentration of products and reactants in a reaction, it would probably change those concentrations as well. I also looked it up and it appears that temperature will affect pH (at least in water).

[Sohan Talluri 1L]

In general, changing the temperature changes the equilbrium constant for a reaction, which for acids and bases would be K_A and K_B respectively. Changing the K_A/K_B changes the [H₃O+] concentration at equilibrium, which would change the pH of the solution (pH = -log[H₃O+]).

Hopefully this helps and please correct me if there are any mistakes.

[Bobak Pourrahimi 2L]

Given temperature is known to affect K values and consequently the concentrations of different elements of a solution, it is certain to affect the pH of a solution, since pH is a conversion of concentration.

[Alison King 3L]

Yes, since equilibrium constants are only for a specific temperature, equilibrium concentrations change depending on the temperature and thus the pH will change

[Srikar_Chintala_1E]

Yes, temperature can affect pH. However, I do not think we have dived into that yet.

[905767718]

Temperature increases the pH of solutions because there are more intermolecular processes occurring that cause the molecules to dissociate.

[Polo Morales 3C]

Yes, since we are calculating pH using a known equilibrium constant, the calculated pH will change if the constant changes. As explained in the lecture, temperature does, in fact, affect the equilibrium constant, and therefore the pH. Hope this helps!

[trevina_brown_2A]

Yes, pH is inversely proportional to the temperature.

[Monse Mata 3D]

As it was stated previously, temperature will affect the pH of acidic and basic solutions.

[405490807]

pH and temperature are inversely related, I think it has something to do with the bonds that are broken as heat increases but I could be mistaken.

[Caitlyn Lo 2F]

Temperature does affect the pH values because they have an inverse relationship

[205783236]

yes it would because increasing the temperature for reactions shifts the reaction equilibrium (shifts it right or left) shifting the reaction would affect the value of the pH

[Rebecca Preusch 2C]

yes pH is inversely proportional to temperature

[rachelsjordan 1K]

They are inversely proportional I think

[Kainath Kamil Dis 2K]

They are inversely proportional

[andreagutierrez 3K]

Yea temperature has an impact since they are inversely proportional.

[Madison Nguyen 3L]

Because temperature changes K, the equilibrium constant, then the pH would therefore be affected.

[Ruben Adamov 1E]

Temperature and pH have an inverse relationship. in other words, when temperature rises the pH decreases and vice versa.
Hope this helps!!

[ThomasL1L]

If the equilibrium concentrations were to change due to an increase/decrease of the temperature then the amount of H+ formed would change meaning the pH of the solution would change.

[Nicole Friday 1E]

Yes, the temperature can impact the pH since pH and temperature are inversely proportional.

[Erin Woolmore 1C]

I believe so, since heating and cooling reactions affects the concentrations of reactants/products and pH is just the -log of the concentration of H+ ions.

[Jessica Sun 2I]

Temperature and pH are inversely related, so temperature does affect pH.

[tristenleem3B]

Temperature and pH are inversely proportional.

[Chelsea Tran 3H]

Yeah, temperature and pH are inversely related.

[Emily Quill 2H]

Hi! Temperature and pH are inversely related as temperature affects the concentrations of H+ and pH=-log[H+].

[Darren Apostol 2L]

K is different for each temperature, and as pH and K for acids are related, temperature affects pH. As stated above, they're inversely proportional.

[Kaitlyn_Urquilla_1I]

Yes, temperature has an impact on the pH of acids and bases since the pH is inversely proportional to temperature.

[Nyah Zhang 1E]

Yes, temperature will affect pH. Changing the temperature would change the K values which would cause the concentrations to change. This will affect the pH of the solution.

[Benicio Rivera 1F]

pH decreases with increase in temperature. But this does not mean that water becomes more acidic at higher temperatures. A solution is considered as acidic if there is an excess of hydrogen ions over hydroxide ions.

[Guadalupe_3B]

Temperature has an impact on pH because pH will decrease as temperature increases. pH and temperature are inversely proportional to each other.

[Maddie Klee 3K]

Hi, yes there is a relationship. pH is inversely proportional to the temperature. This relationship can be understood by knowing that changing the temperature affects the value of K.

[Lindsey Walter 3E]

Changing the temperature of a solution will change the K value of a system. This can also mean a change in Ka or Kb, which will lead to a change in pH.

[kaylasaens2A]

pH and temperature have an inversely proportional relationship.When temperature increases, pH decreases. When temperature decreases, pH increases.

[Kendall Brown]

Changing the temperature will change the Kb and Ka values which will effect the dissociation of the acid or base, which will effect the pH.

[HaleyC 2F]

pH is inversely proportional to the temperature.

[Palig Kechichian 3F]

The increase in temperature is probably associated with dissociation of water molecules, hence increasing the concentration of [H+] ions
