Detailed Solution

(a) Li2O+2KCl→2LiCl+K2OThe above equation is incorrect because amine a stronger base cannot be generated by a weaker base, Li2O(b) CoClNH35++5H+→Co2++5NH4++Cl−The above equation is correct because amine complexes decompose under acidic medium. Thus, the complex [CoCl(NH3)5] decomposes under acidic conditions to give ammonium ions.(c) MgH2O62++EDTA4−→excess NaOHMgEDTA2++6H2OThe above equation is incorrect because the product formed would be [Mg (EDTA)]2-.(d) CuSO4+4KCN→K2CuCN4+K2SO4The above equation is incorrect. Thus, the correct equation is2KCN+CuSO4→K2SO4+Cu+CN2Cyanogen gas
