Increasing/Decreasing pH and buffer solutions
In Brooke's final review worksheet (3/8), there was a problem (#2) where it asks what would increase the pH of a buffer solution. What could we add/remove that would increase or decrease the pH of a solution in general? Thanks in advance!
Re: Increasing/Decreasing pH and buffer solutions
Adding acidic stuff lowers pH and adding basic stuff raises the pH.

Re: Increasing/Decreasing pH and buffer solutions
The transferring of OH- and H3O+ ions, respectively, would bring about change in the pH and buffer solutions.

Re: Increasing/Decreasing pH and buffer solutions
This just means that adding more acid would make the solution more acidic and adding more base would make it more basic. You can also choose a conjugate acid/base that has a lower higher Ka/Kb to adjust the buffer solution pH.
Re: Increasing/Decreasing pH and buffer solutions
I think it is important to remember that we determine pH by the concentration of hydrogen ions in a solution. For that reason, we are able to see that in order to increase/decrease pH and buffer solutions, we need to increase/decrease the H+ ions inside those solutions. Hope that helps!
