A, B and C are three complexes of chromium (III) with the empirical formula H_(12)O_(6)Cl_(3)Cr. All the three complexes have water and chloride ion as ligands. Complex A does not react with concentrated H_(2)SO_(4), whereas complexes B and C lose 6.75% and 13.5% of their original weight, respectively, on treatment with concentrated H_(2)SO_(4). According to the Werner theory, the structure of complex A is represented by :

1.	A, B and C are three complexes of chromium (III) with the empirical formula H_(12)O_(6)Cl_(3)Cr. All the three complexes have water and chloride ion as ligands. Complex A does not react with concentrated H_(2)SO_(4), whereas complexes B and C lose 6.75% and 13.5% of their original weight, respectively, on treatment with concentrated H_(2)SO_(4). According to the Werner theory, the structure of complex A is represented by :
Answer» SOLUTION :`A implies [CR(H_(2)O)_(6)]Cl_(3)`
