3.4 Study the pH titration curve of a monoprotic weak acid with sodium hydroxide and label points A, B and C. (3) "B volume of NaOH added (a) A: Volume of NaOH at the equivalent point, B: volume of NaOH required to neutralize one-half of the acid, C: pH when acid is half neutralized A V (b) A: Volume of NaOH when acid is half neutralized at the equivalent point, B: volume of NaOH required to neutralize one-half of the acid, C: pH at the equivalent point Student self-assessment. MBIA021. (c) A: Volume of NaOH required to neutralize one-half of the acid, B: volume of NaOH at the equivalent point C: pH when acid is half neutralized (u) carangay. (d) A: Volume of NaOH at the equivalent point, B: volume of NaOH when acid is half neutralized, C: pH required to neutralize one-half of the acid 2.10 This carboxyl group ionizes to release (a) hydrogen ions (H') from the COOH group resulting in the positively charged COO* group contributing to the hydrophilic nature of whatever molecule it is found on. (b) hydrogen ions (H') from the COOH group resulting in the negatively charged COO group contributing to the hydrophilic nature of whatever molecule it is found on. (c) hydrogen ions (H) from the COOH group resulting in the negatively charged COO+ group contributing to the hydrophilic nature of whatever molecule it is found on. (d) hydrogen ions (H) from the COO" group resulting in the positively charged COO+ group contributing to the hydrophilic nature of whatever molecule it is found on. 2.11 The carbonyl group (a) have a partially negatively charged oxygen atom that may form hydrogen bonds with water molecules, again making the molecule more hydrophilic. (b) partially negatively charged oxygen atom that may form hydrogen bonds with water molecules, again making the molecule more hydrophobic. (c) partially positive charged oxygen atom that may form hydrogen bonds with water molecules, again making the molecule more hydrophilic. (d) partially negatively charged oxygen atom that may form negative bonds with water molecules, again making the molecule more hydrophobic.
