Homework Answers
1. B2 represents acid HA. when base is added it gets deprotonated and we see a pH rise for the solution.
HA + OH- ---> A- + H2O
2. B3 is an conjugate base A- of acid. When base is added it looses another proton to form A^2- and thus pH increases for the solution.
A- + OH- ---> A^2- + H2O

can someone please help me out with questions 1-5, please
To add more information this was given to me for a lab that used
a weak acid and we added a strong base through titration. We just
observed how the ph changes. Later we then used a buffer with a
weak acid to see how buffers affect ph change. These questions are
basically surrounded around those topics to help us prepare.
However, I'm kinda confused about answering them because weak...

please solve the hilighted Questions
In Activity 1, what happened to the pH of the water sample as 0.1 M HCl was added? How did this compare to what happened with addition of one drop of 0.1 M HCl to each buffer solution? In Activity 1, why did the pH of the buffer solutions change after the addition of 10 drops of 0.1 M NaOH? NaOH is strong base when its added to the solution, its react with the weak...

1. A buffer called "Tris" is widely used in biochemistry. The (neutral) compound "Tris" itself is a weak base, so we'll notate it as "B." The pk, of its conjugate acid (HB) is 8.07. The overall goal of this problem is to calculate the pH change of a Tris buffer upon addition of some strong base. (a) Assume that you have a pH 8.40 Tris buffer...

Acid-Base Titration of a Weak Acid with a Strong Base: Determination of K. Introduction: You will be titrating a solution of a weak acid with 0.100 M NaOH, while monitoring the reaction using a pH meter. Weak acids have characteristic acid-ionization constants, K. The purpose of this lab is to use the titration to determine the value of this constant for the weak acid called “benzoic...
