Solutions: NaCl, C12H22O11, Hal, HC2H3O2, NaOH, NH3. Which of these solution fall into the Dim, Dark or Bright light bulb category?
NaCl, NaOH are strong electrolyte thus, dissociate in solution and give ions and hence conduct electricity and produce bright light.
C12H22O11 is non-electrolyte and thus ions are not obtained and it don't conduct electricity and give dark.
HC2H3O2, NH3 are weak electrolyte thus dissociate weakly and less ions are produced and conduct electricity less and give dim light.
