Title: Quantitative and Qualitative Analysis Purpose: The purpose of this experiment is to learn how to measure the amount of a substance that is present in a chemical compound. A metal carbonate will be analyzed to determine how much CO2 and moles of CO2 are lost. Another experiment will also look into how much water a hydrate loses and determine what type of hydrate it is. Paper chromatography will be used to determine the identity of chemical substances. Lastly, SEM/EDX will be used to d...

Quantitative Chemical Analysis

Lead-based paint (LBP) - Correct answer-Any varnish, shallac, or coating that contains either- 1.0 mg/cm2 - 0.5 % by weight - 5000 ppm - Older instruments could not read accurately at 0.7, so the lead standard was updated to 1.0 Dust sample clearance values - Correct answer-- Floors: 40 μg/ft2 > 10 μg/ft2 (10 μg/ft2 in NY) - Windows: 250 μg/ft2 > 100 μg/ft2 (50 μg/ft2 in NY) - Window wells (troughs): 400 μg/ft2 (100 μg/ft2 in NY) - Samples must be at 1 sq ft > 2 sq ft (can ...
