JEE Advanced Chemistry question
If there is 100% ionisation of this complex. A compound has the empirical formula . When an aqueous solution of this compound is mixed with excess silver nitrate, 2 moles of precipitate per mol of compound. On reaction with excess no is detected, its 1 M solution at 300 K will have osmotic pressure equal to
Answer: (D)
Solution
As established, the compound is [Co(NH_3)_5Cl]Cl_2, which ionises completely as [Co(NH_3)_5Cl]^{2+} + 2Cl^-, giving ions per formula unit. Van't Hoff
