Solution

The correct options are
A On reaction of $A g_{2} C O_{3}$ with $H F$ gives $A g F$
B $A g F$ reacts with $A g$ to give $A g_{2} F$ called silver subfluoride
C $A g$ on heating with $F_{2}$ gives $A g F_{2}$
a) $A g_{2} C O_{3} + 2 H F \to 2 A g F + H_{2} O + C O_{2}$
b) $A g + A g F \to A g_{2} F$
c) $A g$ on heating with $F_{2}$ gives $A g F_{2}$
d) Hydrated AgF is colourless while pure Anhydrous AgF is yellow in colour.
