point of the solution Sallple of Co NH CH CHÁNH) point of the solution is -0.87C. How ma of water is 1.86°C/molal (a) 2 (a) LL12) 664 (d) [Pt(H20) 2014].4H20 (C) [Pt(H20)3C13]C1-3H20 23. A complex is represented as CoCxNH. Its 0.1 molal solution in water showS AT = 0.558 K Kf for H, is 1.86 K molality -1. Assuming 100% ionisation of complex and co-ordination number of Co is six, calculate formula of complex: (b) [Co(NH2)5Cl]Cl2 (a) [CO(NH3)]C13 (d) none of these (c) [Co(NH3)4C12]CI inne will be highest for: (6) 3 84. An aqueous solution contains 3% and 1 freezing point of solution? (K = 1.86 (a) -1.172°C (b) -2.27°C
