11.12—CORE PRACTICALS 9a and 9b Following the rate of the iodine-propanone reaction by a titrimetric method and investigating

CORE PRACTICALS 9a and 9b Following the rate of the iodine-propanone reaction by a titrimetric method and investigating a ‘clock reaction’ (Harcourt-Esson, iodine clock).

Use —core practicals 9a and 9b following the rate of the iodine-propanone reaction by a titrimetric method and investigating to connect the rule to the data and decision in the question.

This matters because —core practicals 9a and 9b following the rate of the iodine-propanone reaction by a titrimetric method and investigating determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —core practicals 9a and 9b following the rate of the iodine-propanone reaction by a titrimetric method and investigating to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —CORE PRACTICALS 9a and 9b Following the rate of the iodine-propanone reaction by a titrimetric method and investigating is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
