Write the IUPAC name of the complex [Cr(NH3)4Cl2]+. What type of isomerism does it exhibit?
In reference to Freundlich adsorption isotherm, write the expression for adsorption of gases on solids in the form of an equation.
Based on the type of particles of dispersed phase, give one example each of associated colloid and multimolecular colloid.
Account for the following:
(i) PCl5 is more covalent than PCl3.
(ii) Iron on reaction with HCl forms FeCl2 and not FeCl3.
