प्रश्न

X - \[\ce{HCl <=> H^{1+} + Cl-}\] (in solution state)

Y - \[\ce{PbBr2 <=> Pb^{2+} + 2Br^{1-}}\] (in molten state)

From the above reaction X or Y, identify the reaction which exhibit:

electrolytic dissociation

टिप्पणी लिखिए

उत्तर

'Y' Electrolytic dissociation of PbBr2 occurs when energy in the form of heat induces molecules to generate ions, breaking the electrostatic interaction between ions.
