Question: Mathematical Calculate the hydroxide ion concentration OH for each of
Mathematical Calculate the hydroxide ion concentration, [OH−], for each of the materials used in Question 24.
Answer to relevant QuestionsDefine the following: (a) Acid dissociation constant (b) Acid strength (c) Amphipathic (d) Buffering capacity (e) Equivalence point (f) Hydrophilic (g) Hydrophobic (h) Nonpolar (i) Polar (j) Titration Mathematical What is the ratio of HEPES / HEPES-H1 in a HEPES buffer at pH 7.9? Which would you think would be a stronger interaction and why: an interaction between a sodium ion and the partial negative charge on the oxygen in ethanol (CH3CH2OH), or the interaction between two ethanol molecules? Consider the following peptides: Phe! Glu! Ser! Met and Val! Trp! Cys! Leu. Do these peptides have differ-ent net charges at pH 1? At pH 7? Indicate the charges at both pH values. MatheMatical Draw structures of the following amino acids, indicating the charged form that exists at pH 4: histidine, aspara-gine, tryptophan, proline, and tyrosine.
