6.23 Buffer Solutions

Postby asannajust_1J » Mon Jan 20, 2020 3:43 pm

Not sure how to answer this problem, A buffer solution containing equal amounts of acetic acid and sodium acetate is prepared. What molar concentration of the buffer must be prepared to prevent a change in the pH by more than 0.20 after the addition of 1.00 mL of 6.00 m HCl(aq) to 100.0 mL of the buffer solution?
I calculated the amount of H3O+ that forms when HCl is placed in water, but not sure how to continue...

I wouldn't worry about it since it's not on the syllabus... When an exercise is not on the syllabus it sometimes means Dr Lavelle didn't teach the content, so we aren't able to solve it anyways

We only learned to calculate the pH of buffer solutions and didn't go into how they actually resist changes in pH. I don't think its part of the 14B curriculum and certainly wouldn't worry about it for the upcoming test.
