Chemistry of Life: Acid, Base, pH and Buffers Flashcards
1
Q
Analyze how acidity is related to molecular ionization
A
The stronger the electronegativity within an acid the more easily it releases a hydrogen proton. Strong acids are completely ionizable. Weak acids partially ionizable
2
Q
List major acids and bases in biological systems
A
Acids- lactic acid, HCl, amino acids
Base- dihydrogenphosphate ion, bicarbonate ion, amino acids
3
Q
Determine [acid] and pH values from strong or weak acids
A
pH= pKa + log [A-]/[HA]
4
Q
Based on pKa, distinguish between strong and weak acids
A
Small pKa= strong acid
Large pKa= weak acid
