We did a lab. The reaction of zinc and iodine.

We put 1 g of zinc with 1 g of iodine.. and used alcohol.
Is the equation Zn + I2 ----> ZnI(2)?

The moles of Zn atoms consumed were .003 mol.
The moles of I atoms consumed were .004 mol.

The class got a ratio and we averaged it.. it was 1:1.98

What does this ratio mean? Could someone explain this?

  • Chemistry -

    1:1.98 rounds to 1:2 which means the formula is ZnI2.
