What is the discussion of discussion of experiment determination of the formula unit of zinc chloride?

Answer 1

The theorecal formula unit will be 1 Zn and 2 Cl so the theoretical formula unit is ZnCl2. But the calculated formula unit is 2 Zn and 3 Cl so the formula unit will be Zn2Cl3. There is a difference because the experiment was done in an open place where there is air presence and we weigh balance also not in a close condition, so there is some error. To overcome this error, the weigh balance should have its cover to prevent the air weighed too.

Answer 2

The experiment aims to determine the formula unit of zinc chloride by creating a known quantity of the compound through a precipitation reaction with silver nitrate. By quantifying the amount of silver chloride precipitate formed and relating it back to the initial masses of reactants, one can calculate the formula unit of zinc chloride. The discussion would cover factors such as experimental error, sources of uncertainty, and how well the results align with the theoretical formula unit.
