Which one of the following complexes will consume more equivalents of aqueous solution of Ag(NO3)?

Multiple Choice Options

  • A Na3[CrCl6]
  • B [Cr(H2O)5Cl]Cl2
  • C [Cr(H2O)6]Cl3
  • D Na2[CrCl5(H2O)]

Step-by-Step Verified Solution

[Cr(H2O)6]Cl3 has the highest primary valency among the given complexes, that is, three, therefore, it will consume three moles of AgNO3 and precipitate three moles of AgCl.

[Cr(H2O)6]Cl3 + 3AgNo3 → 3AgCl + [Cr(H2O)6](NO)3
