Homework Answers
Solution :-
PBS does not contains only sodium chloride salt because sodium chloride is the neutral salt therefore the saline solution will have pH 7, but PBS saline is having pH 7.4 that means it is having basic pH therefore the PBS saline must contains some conjugate base salt of weak acid so that it can have basic pH.
So from the pH value we can confirm that along with sodium chloride some other salt would also present in the solution.

In lab, we have been using PBS. This is phosphate buffered
saline. Phosphate Buffered Saline is usually 25mM to 100mM
Phosphate Buffer with 137mM NaCl added and often at pH 7.4. You
need to make 1L of 50mM PBS. The buffer is 50mM and the salt
remains at 137mM.
You have the following reagents on the
shelf:
- NaCl (MW = 58.44

Phosphate buffered saline (PBS) is a buffer solution commonly used in biological research. The buffer helps to maintain a constant pH. The osmolality and ion concentrations of the solution usually match those of the human body. A) You need to prepare a stock solution at pH 7.00 with KH2PO4 and Na2HPO4 (pKa =7.21). What would be the respective concentration of these substances if you wish to obtain the final phosphate concentration [HPO4 −2 ] + [H2PO4 − ] = 0.3...
