Answer 1

1) put them into the solution of bromine, the substance which makes the solution lose its colour is NaI
2NaI + Br2 => 2NaBr + I2
2) dissolve them in water, barium sulfate is the only one which cannot be dissolved in water
3) Na2CO3 + 2HCl => 2NaCl + H2O + CO2
NaHCO3 + HCl => NaCl + H2O + CO2

Answer 2

1.NaCl and NaI
