Which one of the following statements is correct?
From a mixed precipitate of AgCl and AgI, ammonia solution dissolves only AgCl
Ferric ions give a deep green precipitate on adding K4Fe(CN)6 solution
On boiling a solution having K+, Ca2+ and HCO3- ions, we get K2Ca(CO3)2
Manganese salts give a violet borax bead test in the reducing flame
As we have learnt,
The reaction occurs as follows:
Fe3+ ions give deep violet colour with K4Fe(CN)6. On boiling K+, Ca2+ and HCO3- containing solution, CaCO3 is formed.
Manganese salts give colourless bead in borax bead test.
Therefore, Option(1) is correct.
