Phospate Buffer System Flashcards
1
Q
The phosphate buffer system consists of
A
The anion dihydrogen phosphate, H2PO4, which is a weak acid.
2
Q
The reversible reaction involved is
A
Dihydrogen phosphate to hydrogen plus mono hydrogen phosphate
H2PO4 ↔️ H + PO4
3
Q
The phosphate buffer system is important in buffering the pH of
A
The ICF
And
In stabilizing the pH of urine
4
Q
In addition, cells contain a
A
Phosphate reserve in the form of the weak base sodium monohydrogen phosphate (Na2HPO4)
5
Q
The dissociation of sodium monohydrogen phosphate provides additional
A
Monohydrogen phosphate for use by this buffer system
2Na + HPO4 ↔️ Na2HPO4
