Compare the change in pH with the addition of acid and base to deionized water and to your buffer. Explain the differences.
deionzied water ph= 4.57
buffer ph= 4.58 diluted water ph= 4.54
deionized water + HCL ph= 2.01
Deionized water + NaOH ph= 11.23
Buffer + HCL ph=3.82
Buffer + NaOH ph= 5.46

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...
