Q11 / 125 · BITSAT 2015 · Chemistry

Some salts containing two different metallic elements give test for only one of them in solution, such salts are

  • A
    double salts
  • B
    normal salts
  • Correct answer
    C
    complex salts
  • D
    None of these

Solution

Complex compounds contains two different metallic elements but give test only for one of them. Because complex ions such as [Fe $\left.(\mathrm{CN})_{6}\right]^{4-}$ of $\mathrm{K}_{4}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right],$ do not dissociate into Fe $^{2+}$ and $\mathrm{CN}$ -ions.

Hence, the correct answer is option: 'C'.
