  1. INORGANIC CHEMISTRY • METALLURGY • CO-ORDINATION CHEMISTRY & TRANSITION ELEMENTS • QUALITATIVE ANALYSIS • PREPARATION & PROPERTIES I) METALS & their compounds II) NON-METALS & their compounds • STRUCTURES of compounds

  2. METALLURGY • Self reduction (Cu & Pb) • Carbon reduction (Fe & Sn) • Electrolytic reduction (Mg & Al) • Cyanide process (Ag & Au) 1. Name of ores with formula. 2. Different steps of extraction with reactions. • Extraction of metals Iron , Copper , Aluminium , Lead , Tin , Magnesium , Silver , Gold , Zinc.

  3. QUALITATIVE ANALYSIS • Make a chart. • Initially, revise it daily • Go through JEE syllabus . • Color the compound in which it precipitates.

  4. 1st GROUP (Ag+ , Pb+ , Hg2+2) • GROUP REAGENT : dil. HCl • All chlorides r water insoluble. • PbCl2 is soluble in hot water

  5. FLOW CHART • PbCl2 , AgCl , Hg2Cl2 • Hot water • f r • PbCl2 AgCl,Hg2Cl2 • NH4OH • fr • Ag(NH3)2Cl NH2HgCl +Hg • (Black ppt.)

  6. 5. Keep it in front of you when you solve the problems initially. 6. Understand clearly the difference between the precipitate & solution. 7. Practice with subjective questions. 8. Revise it regularly.
