Final answer:
A gravimetric analysis is conducted in this experiment to determine the percent by weight of lead. It is a quantitative analysis method that involves separating the analyte from a sample and calculating its concentration based on mass measurements.
Step-by-step explanation:
A gravimetric analysis is conducted in this experiment. It involves separating the analyte from a sample through a physical or chemical process and then determining its mass to calculate its concentration. In this specific experiment, the percent by weight of lead is determined by subjecting the sample to a precipitation reaction, isolating the lead precipitate, and weighing it. This falls under the category of quantitative analysis as it aims to determine the exact concentration of lead in the sample.
