test 7 acids and bases review Flashcards
1
Q
A hydrogen ion is a
A
- single free proton released from a hydrogen atom
2
Q
Acids
A
- Molecules that contain hydrogen atoms that can release hydrogen ions into a solution
3
Q
Bases
A
- Ions or molecules that can accept a H+
4
Q
Acidosis
A
Excess H+
5
Q
Alkalosis
A
Excess removal of H+
6
Q
Strong Acid
A
- rapidly dissociates and releases especially large amounts of H+ in solution
7
Q
Weak Acid
A
- less likely to dissociate their ions and release H+ with less vigor
8
Q
Strong Base
A
- reacts rapidly and strongly with H+ and quickly removes them from solution
9
Q
Weak Base
A
- binds with H+ much more weakly
10
Q
Most acids and bases in the extracellular fluid are
A
- weak acids and bases
11
Q
Normal H+ blood concentration, normal variation, and extreme range
A
- Normal blood concentration: 0.00004 mEq/L = 0.00000004 Eq/L = 40 nEq/L
- Normal variation: 3 to 5 nEq/L (37 to 43 nEq/L)
- Extreme range (without causing death): 10 to 160 nEq/L
12
Q
pH calculation
A
pH = log (1 / [H+]) = -log [H+]
- [H+] HAS TO BE IN Eq/L
