Redox + Electrochemistry
Oxidation number rules, balancing in acidic/basic medium (ion-electron method), disproportionation — then EMF, Nernst at non-standard log values, Kohlrausch law, electrolysis quantitative problems.
Lock this in. Assign oxidation numbers first — every Redox and Electrochemistry question in BITSAT starts here. Memorise log 2 = 0.30, log 3 = 0.48.
