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

Re: pH
In general, changing the temperature changes the equilbrium constant for a reaction, which for acids and bases would be KA and KB respectively. Changing the KA/KB 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.

Re: pH
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.

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

Re: pH
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!

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

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

Re: pH
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.

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

Re: pH
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.

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

Re: pH
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.

Re: pH
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.

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

Re: pH
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.

Re: pH
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.

Re: pH
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.

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