IB Chemistry Internal Assessment Exemplar: To what extent does the ionic strength of 0.5 M salt solutions (NaCl, KCl, CaCl₂, and MgSO₄) correlate with changes in dissolved oxygen concentration in distilled water at 20°C (±0.5°C), and how can the observed rela8onship be explained by the diﬀerential eﬀects of monovalent versus divalent ions on water's oxygen-carrying capacity?
