Value of Ka, Kw, Kb

Postby Andrea_Torres » Thu Jan 23, 2020 6:34 pm

Do they have specific values? I was doing problems 6D.15 and 6D.17 and they both have the same values.

Kw has a specific value at 25 degrees C (1.0x10^-14). Kw relates to Kb and Ka by Kw=Ka*Kb.

Ka and Kb are specific to a reaction at a specific temperature

Kw always is 10^-14 at 25 degrees, but Kb and Ka will change based on the reaction.

At 25 degrees Celcius, Kw is measured to be 1.0*10^-14. Ka,Kb, and Kw varies by temperature.
