Question

Which one of the following statements is correct? (A) Manganese salts give a violet borax- bead test in the reducing flame (B) From a mixed precipitate of AgCl and AgI, ammonia solution dissolves only AgCl (C) Ferric ions give a deep green precipitate on adding potassium ferrocyanide solution (D) On boiling a solution having K +, Ca 2+ and HCO 3- ions we get a precipitate of K 2 Ca ( CO 3)2

NH 3 -an inorganic solvent. Agl is having much higher covalent characteristics in comparison to AgCl.

Q. Which one of the following statements is correct?

Manganese salts give a violet borax- bead test in the reducing flame

From a mixed precipitate of $A g Cl$ and $A g I$ , ammonia solution dissolves only $A g Cl$

Ferric ions give a deep green precipitate on adding potassium ferrocyanide solution

On boiling a solution having $K^{+}, C a^{2 +}$ and $H C O_{3}^{-}$ ions we get a precipitate of $K_{2} C a (C O_{3})_{2}$

$N H_{3}$ -an inorganic solvent.

Agl is having much higher covalent characteristics in comparison to $A g Cl$ .
