A small amount of NaOH is added to a weak acid buffer system. Describe what happens in terms of possible reactions and changes in pH.
For the questions below be sure to show your work as well as the answer to the question.
In this week's lab you made 100ml of 10x PBS by dissolving 8 g NaCl, 1.2g Na₂HPO4 and 0.2 g
KH₂PO4 in water. You then adjusted the pH to 7.0.
A) How many mg of KH₂PO4 did you weigh out?
B) How many liters of 10x PBS did you make?
C) What is the final concentration of NaCl in your solution? (The molecular weight of NaCl is
58.44 g/mol)
D) What is the final concentration of Na₂HPO4 in your solution? (The molecular weight of
Na₂HPO4 is 141.96 g/mol)
E) What is the final concentration of KH₂PO4 in your solution? (The molecular weight of KH₂PO4
is 136.1 g/mol)
F) What is the hydrogen ion concentration of your solution (pH=7.0)?
G) If the initial pH of your solution was 6.29 would you need to add an acid or a base to adjust
the pH of a solution to pH 7.0?
10x PBS is a concentrated stock solution that is used to make more dilute solutions of PBS.
Starting with your 10xPBS stock solution, how would you…
