When H2SO4 is added to PbI2, a precipitate of PbSO4 forms. The PbSO4 is then filtered from the solution, dried, and weighed. If the recovered PbSO4 is found to have a mass of 0.0471 g, how many moles of iodide ions were in the original solution?

Explanation:

Hello,

In this case, the undergoing chemical reaction is shown below:

Thus, we obtain 0.0471 g of lead (II) sulfate, the iodide ions  in the original solution are computed below by stoichiometry, taking into account that into 1 mole of lead (II) iodide there are 2 moles of iodide ions:

Best regards.

-be a crystalline solid

- be soluble in water

-conduct electricity

hope this : )

3 hours because it is a decent distance.
