Concept explainers
(a)
Interpretation:
The compound (s) that conduct only very weak electricity when dissolved in water should be identified.
Concept introduction:
Acids can donate the
strong acids or strong bases are ionize in water very easily, weak acid or weak bases are ionize very slowly.
strong acid and sarong base are one that completely ionizes (dissociates) in a solution (provided there is sufficient solvent). In water, acid HA dissolves and gives
Conductor of electricity depends on the movements of the ions in solution, ions gets separated, it behaves as strong conductor of electricity. If the ions not completely dissociate that will be a very weak conductor of electricity
Strong electricity conductors are strong acids and weak bases.
Weak electricity conductors are weak acid and weak bases.
Soluble compounds in water
Almost all the salts of
Almost all the salts of
Salts of F- are soluble. But some of the fluoride salt of
Salts of
Insoluble compounds in water:
Most of the salts of
Most of the metal hydroxides and oxides are insoluble in water bit some of the alkali metal hydroxides,
Water soluble compounds are ionize in water and conduct the electricity, strongly conduct the electricity compounds are completely soluble in water. Slightly soluble compounds are weak conductor of electricity.
