19.11—Experiments to investigate the characteristic behaviour of amino acids limited to: i acidity and basicity and the formation

Be able to describe experiments to investigate the characteristic behaviour of amino acids limited to: i acidity and basicity and the formation of zwitterions ii effect of aqueous solutions on plane-polarised monochromatic light iii formation of peptide bonds by condensation polymerisation.

Use —experiments to investigate the characteristic behaviour of amino acids limited to: i acidity and basicity and the formation to connect the rule to the data and decision in the question.

This matters because —experiments to investigate the characteristic behaviour of amino acids limited to: i acidity and basicity and the formation determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —experiments to investigate the characteristic behaviour of amino acids limited to: i acidity and basicity and the formation to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Experiments to investigate the characteristic behaviour of amino acids limited to: i acidity and basicity and the formation is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
