What is Lead to Iodine Ratio Analysis about?

1) Special solutions of lead nitrate and potassium iodide were made using molarity to determine the number of atoms or each substance. 2) Predictions were made about what ratios of lead to iodine atoms would form direct relationships on a graph versus leveling off. 3) Results from the lab showed the graph formed was not a direct relationship, indicating the ratio could not be 1:1, and iodine ran out before lead, suggesting the ratio must be PbI2.
