Iodine is the only halogen that occurs in a positive oxidation state, in NaIO₃ impurities within Chile saltpeter, NaNO₃.(a) Is this mode of occurrence consistent with iodine’s location in the periodic table? Explain

Respuesta :

The number of moles of NalO3 present in the deposit is 83.23 mol NaIO3.

The mass of NaNO3 deposit present is 2000. Ib Molar mass of NaNO3 is 85.03 g/mol .

Calculate the number of moles of NaNO3

present in the 2000 pounds of NaNO3.

2000 lb x (453.592 gX 1 mol NaNO3)/ 1 lbX 85.03 g

          =1.067x10^4 mol NaNO3

The percentage of NaIO3  present in the NaNO3 deposit is 0.78 mol%.

Multiply the number of moles of NaNO3 with the mole percentage of the NaIO3, to get the actual number of moles of  NaIO3 present in the deposit.

0.78% (1.067×10* mol NaNO3)=0.78 mol NaIO3/100 mol NaNO,

                                                 = 83.23 mol

Thus, the number of moles of NalO3 present in the deposit is 83.23 mol NaIO3
