InterviewSolution

1.	Some salts although containing two different metallic elements give test for one of them in solution. Such salts are:A. Complex saltsB. Double saltsC. Normal saltsD. None .
Answer» Correct Answer - A Complex compounds or complex salts containing two different metallic elements give tests for only one element. For example potassium hexacyanoferrate (II), `K_(4)(Fe(CN)_(6)]` give tests only for `K^(+)` ions and not for `Fe^(2+)` ions. `K_(4)[Fe(CN)_(6)]hArr 4K^(+) + [Fe(CN)_(6)]^(4-)`
