Van't Hoff Equation Test #2

Postby Hailey Boehm 2H » Tue Mar 12, 2019 2:56 pm

On the Van't Hoff Equation on Test #2, how do we plug the values into the equation (I assume the numbers each section had are different, so just a general explanation would work)? Is Kw-10-14 considered k1? and once we obtain a values for k2, how can we determine if the solution is acidic or basic? Thank you!

Yes, in the test, Kw was K1. Once you determine the K2 value, you can use the rule: K = [H+][OH-]. This means you can square root the K2 value to get [H+], which you can then plug in pH = -log[H+]. The pH value you calculate will be the new pH value for neutral solutions. For example, say that you calculate 6.8. 7 is greater than 6.8, so a pH of 7 would be basic.
