IB Chemistry SL IA Example 2 (20/24)
This Chemistry SL IA scored 20/24 (Grade 7) and was created by a 44/45 student for the November 2022 session. This IA is up to date with the newest 2016 IB Chemistry SL syllabus.
Research Question: What effect does the concentration (𝐦𝐨𝐥 𝐝𝐦−𝟑) of the copper (II) sulphate (𝐂𝐮𝐒𝐎𝟒 (𝐚𝐪)) electrolyte (at 0.2, 0.4, 0.6, 0.8 and 𝟏 𝐦𝐨𝐥 𝐝𝐦−𝟑) have on the voltage (V) of a copper-zinc Daniell cell, with a 𝟏 𝐦𝐨𝐥 𝐝𝐦−𝟑 zinc (II) sulphate (𝐙𝐧𝐒𝐎𝟒 (𝐚𝐪)) electrolyte at 298.15K?
This resource is a brilliant exemplar of the Chemistry SL Internal Assessment and can be used as a model for both the structure and the level of analysis required to achieve a strong Grade 7 in the task.
