Ferric hydroxide colloidal solution. Experiment 1.5 uses hydrolysis of ferric chloride to prepare this lyophobic sol for surface chemistry study.
Higher temperature increases kinetic energy, reducing the time for sulphur precipitation. This is studied in Chemical Kinetics (Experiment 2.2).
Variation of cell potential with change in CuSO₄ and ZnSO₄ electrolyte concentrations at room temperature (Experiment 4.1, Electrochemistry).
Rf = Distance moved by solute / Distance moved by solvent front. Used for pigment separation from leaves (Experiment 5.1).
Acetanilide. Experiment 7.1 involves acetylation of aniline using glacial acetic acid or acetic anhydride.
Ferrous ammonium sulphate, known as Mohr’s salt with formula FeSO₄.(NH₄)₂SO₄.6H₂O, prepared as green crystals.
Using Bayer’s test (dilute KMnO₄) or bromine water test. Decolorization indicates presence of double/triple bonds (Experiment 8.1).
Potassium permanganate (KMnO₄). Experiment 10.1 determines its molarity and strength using oxalic acid as primary standard.
By paper chromatography using suitable solvent. Rf values differ, allowing separation and identification (Experiment 5.2).
Mohr’s salt (ferrous ammonium sulphate) solution of M/20 concentration is used, followed by redox titration with KMnO₄.
