Question
Describe how sodium dihydrogen phosphate can be used as a pH buffering agent.
Step 1
Understanding sodium dihydrogen phosphate: Sodium dihydrogen phosphate (NaH2PO4) is a salt of a strong acid (phosphoric acid, H3PO4) and a weak base (sodium hydroxide, NaOH). It is a white, crystalline solid that is soluble in water. Show more…

You have a solution of sodium dihydrogen phosphate. What salt could you add to this solution to make a buffer?
Use Table 7 to calculate the pH of a buffer solution made from equal amounts of sodium monohydrogen phosphate and potassium dihydrogen phosphate.
The dihydrogen phosphate ion has the ability to act as an acid in the presence of a base and as a base in the presence of an acid. What is this property called? Illustrate this behavior with water by writing Brønsted-Lowry acidbase reactions. Also illustrate this property by selecting a common acid and base to react with the dihydrogen phosphate ion.
