A solid compound (A) has the formula CoCl3 4NH3 2H2O. One mole of this salt in aqueous solution gives 3 moles of AgCl with excess of silver nitrate. On reaction with conc. H2SO4, (A) does not lose water. But on strong heating, it loses water giving a complex (B) without changing the oxidation state and coordination number of central metal ion. name b

A solid compound (A) has the formula CoCl3 4NH3 2H2O. One mole of this salt in aqueous solution gives 3 moles
Explanation:
The complex compound (A) is given as "CoCl3 4NH3 2H2O."
To identify the complex formed when (A) loses water upon strong heating, we can analyze the given information. Since it's stated that the complex (B) doesn't change the oxidation state or coordination number of the central metal ion (cobalt, Co), we can infer that the complex formed upon heating would involve the same cobalt ion (Co^2+ in this case).
When (A) loses water, it might form the complex CoCl3 4NH3, which retains the Co^2+ ion and maintains its coordination number. So, the complex (B) formed upon heating might be "CoCl3 4NH3."
Please note that this is an educated guess based on the provided information, and the exact nature of complex (B) would depend on the specific conditions and properties of the compound.
