1. The pH of an acetate buffer is determined to be
4.36. What is the [CH3COOH]/ [CH3COO-] ratio in
this buffer? Acid : Base = 10(pKa -
pH)
- 2 : 1
- 2.5 : 1
- 10 : 1
- 1 : 2
2. As environmental pH decreases,
- molecules and ions gain protons, becoming more positively
charged.
- molecules and ions lose protons, becoming more positively
charged.
- molecules and ions gain protons, becoming more negatively
charged.
- molecules and ions lose protons, becoming more negatively
charged
