Water and Buffer Flashcards
1
Q
Properties of water.
A
- It is highly reactive.
- Transport of nutrient by virtue of solubility.
- Very good solvating properties.
- Use as catalyst
- Participant in some reactions like hydrolysis etc.
2
Q
It controls basicity and acidity of the solution by changing it’s pH?
A
Buffer
3
Q
Buffer capacity in pH?
A
pH =pKa ± 1
4
Q
Formula of pH?
A
pH = -log [H₃O⁺]
5
Q
Formula of pH related to buffer system?
A
pH = pKa + log (P)/(R)
where: pKa = -log Ka
6
Q
Normal pH of human?
A
pH 7.3-7.5
