Expert Preparation Strategy
Quick Tip: When dealing with organic acids and commercial salts, create a quick mental mapping table. For example, directly link 'Apple' to 'Malic Acid' and 'Ant Sting' to 'Formic Acid'. For inorganic compounds, always memorize their common household names directly alongside their chemical formulas—such as knowing that Calcium Oxychloride (CaOCl2) is simply Bleaching powder, or Sodium Bicarbonate (NaHCO3) is Baking soda. Mastering these direct conceptual pairs will help you eliminate wrong options instantly and save crucial seconds during the actual examination.
