Question
Please explain how to obtain answers. Be very descriptive. Thanks.
9. A titration occurs when an acid and base is added together, forcing one to dissociate. Neutralization refers to the “point” when there’s an equivalent amount of acid and base. (A better term is actually equivalent point). How does that differ from the pKa “point” or value ?
10. Find out why amino acids have at least 2 pKa values.
11. Label the components of the cell in the figure and states if it is a plant or an animal cell and why? (You can access the figure in the assignment section)
12. States the differences between an animal cell and a plant cell.
13. What is the derivation of the Henderson-Hasselback equation? Show all steps.
Explanation / Answer
9. End point or equivalence point of an acid base titration is the point when equal equivalent of acid and base have reacted. It is detected with the help of a indicator.
While Pka values are calculated at dissociation equilibrium of an acid or base.
10. An amino acid have at least one acidic and at least one basic group. So it must have at least two Pka values.
