Class 10 Chemistry Chapter 10 Short Questions
- Strong acids or bases ionize completely in water while weak acids and bases ionize partially.
- According to Arrhenius’s concept, acids produce H+ ions in an aqueous solution while bases produce OH-ions in an aqueous solution.
- According to the Bronsted-Lowry concept, acids are proton donors and bases are proton acceptors, so this concept is applicable to non-aqueous solutions.
- A substance that can behave as an acid as well as a base depending upon the nature of other substances is called amphoteric.
- According to Lewis’s concept; acids are electron pair acceptors and bases are electron pair donors.
- The product of any Lewis acid-base reaction is a single species called adduct.
- The “p” scale is the conversion of very small figures into positive figures by taking the common logarithm of the small figure and multiplying it by 1.
- pH scale is the negative logarithm of the concentration of hydrogen ions.
- A substance having a pH less than 7 is acidic while a substance having a pH more than 7 is basic. A substance of pH 7 is called neutral.
- Salts are ionic compounds made up of metallic cations and non-metallic anions.
- 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.
