316932 When iodine reacts with \(\mathrm{NaF}, \mathrm{NaBr}\) and \(\mathrm{NaCl}\),

1 It gives mixture of \(\mathrm{F}_{2}, \mathrm{Cl}_{2}\) and \(\mathrm{Br}_{2}\)
2 It gives chlorine
3 It gives bromine
4 No reaction
CHXI11:THE P-BLOCK ELEMENTS

316933 Solubility of iodine in water may be increased by adding

2 \(\mathrm{HBr}\)
3 \(\mathrm{HCl}\)
4 \(\mathrm{H}_{2} \mathrm{~S}\)
