Ch#8-Acids, Bases and Salts Chemistry Notes FSc Pre-Engineering 2016-17 New Course FBISE

In Eighth chapter (Ch#8-Acids, Bases and Salts), the students will learn about acids, bases and amphoteric compounds, the significance of acid base reactions in daily life (food preservation, allergic reactions, importance of iodine in salt, gastric acidity, curdling of milk), calculation of molarity, molality and strength of given sample solutions based on acid-base titration, definition of acids and bases according to Lowry – Bronsted theory, definition of conjugate acid and conjugate base, comparison of the strength of conjugate acids and bases, explanation of the ionization constant of water (Kw), comparison of the strength of acids and bases using pH and pOH, derivation of the dissociation constants of acid, base and water (Ka, Kb and Kw), calculation of the + H3O concentration by using the given Ka and molar concentration of weak acid, explanation of the term “levelling effect”, definition of Lewis acids and bases along with examples, classification of the given compounds (e.g. NH3, AlCl3, BF3, etc.) as Lewis acids or bases, definition of buffer solution, state the importance of buffer in daily life, the preparation of different types of buffer, explanation with the help of equations the buffer action to maintain pH of solutions, definition of hydrolysis, explanation of the types of salt on the basis of hydrolysis and differentiate between hydrolysis and hydration.
