Consider the following information for a... 1. (ii) On dissolving ammonium chloride (NH4Cl) in water in a test tube, the test tube becomes cold as it takes heat from the surrounding water. (iii) Paint is applied on iron articles to prevent them from rusting (corrosion). b) What can you say about the relative magnitudes of the lattice energy of ammonium chloride and its heat of hydration? In order to account for a solid dissolving in a liquid, we have to consider the enthalpy of lattice dissociation, which is the energy required for one mole of solid to dissociate into its gaseous ions, and the enthalpy of hydration, the energy required for one mole of gaseous ions to produce dissolved ions in an aqueous solution. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. why does ammonium chloride conduct electricity when dissolved in water and not when it is solid???
