Key Points of Chapter 10 Acid Base and Salts:
- Strong acids or bases ionize completely in water while weak acids and bases ionize partially.
- According to Arrhenius concept, acids produce H+ ions in aqueous solution while bases produce OH- ions in aqueous solution.
- According to Bronsted-Lowry concept, acid are proton donor and bases are proton acceptor, so this concept is applicable to non-aqueous solutions.
- A substance that can behave as an acid as well as base depending upon the nature of other substances is called amphoteric.
- According to Lewis concept; acids are electron pair acceptors and bases are electron pair donors.
- The product of any Lewis acid base reaction is a single specie called adduct.
- “p” scale is the conversion of very small figures into positive figures by taking the common logarithm of the small figure and multiplying it with-1.
- pH scale is the negative logarithm of concentration of hydrogen ions.
- A substance having pH less than 7 is acidic while a substance having pH more than 7 is basic. A substance of pH 7 is called neutral.
- Salts are ionic compounds made up of metallic cation and non-metallic anion.
- Different methods for the preparation of soluble and insoluble salts have been discussed.
- Normal salts are made up of cations of strong bases and anions of strong acids.
- Acidic salts are made up of cations of weak bases and anions of strong acids.
