How are Nonvolatile/Fixed acids created?
Breakdown of proteins
Examples of Nonvolatile/Fixed acids
Sulfuric acid (H2SO4) & phosphoric acid (H3PO4)
Elimination of Nonvolatile/Fixed acids
Nonvolatile/Fixed acid is removed through the Kidney
What removes Nonvolatile/Fixed acids in the body?
Kidney
What removes volatile acids in the body?
Lungs
Another name for Nonvolatile acid?
Fixed acid
What do acids release in measurable amounts?
Acids release hydrogen ions (H+) in measurable amounts
What happens, when acids dissolve in water solutions?
Releases Protons (+) & anions (-)
Acidity of a solution reflects?
Free H+

, Strong acids
Dissociate completely and liberate all H+. Which dramatically
changes the pH of the solution
Strong acids dramatically change?
pH of the solution
Strong acid example
HCl in water breaks into H+ and Cl- ions only
Weak acids
Do not dissociate completely. Have much smaller effect on pH
(less free H+)
Weak acid example
Carbonic acid (H2CO3)
How do weak acids affect pH compared to strong acids?
Weak acids have much smaller effect on pH. (Less free H+)
True or False? Volatile acid vaporizes easily & can be exhaled.
True
H2CO3
Carbonic acid
Carbonic acid is in equilibrium with?
Dissolved CO2 (reversible effect)
Respiratory acid is excreted?
Via the lungs (exhale out)
