Density Column Project

Background Density is the ratio of the mass and volume of a substance. Each substance has a specific value for density. If a substance floats in water, its density is less than that of water. If a substance sinks in water, its density is greater than that of water.

Getting Started… Here are a list of websites that might help: 1. ny6d.html 2.media.nasaexplores.com/lessons/ /9-12_1.pdf 3.genchem.chem.wisc.edu/demonstrations/ Gen_Chem_Pages/01mattermixpage/hou sehold_density_column.htm 4.membership.acs.org/t/tag/experiments.htm

Pre-Lab Questions 1.Define the terms: density, intensive and extensive properties. 2.What units are usually used to express density?

Procedure 1.You will find five liquids with different densities using the internet or textbook. 2.Gather those liquids that you have researched. 3.Slowly pour the most dense liquid into the container and continue until all five liquids have been added. The liquids should form layers. 4.Cap the container and write your name on it.

Post-Lab Questions 1.What are your five liquids? 2.Which of your liquids has the greatest density? What is its density? 3.What are the densities of the rest of your liquids? 4.How could density be used to identify an unknown substance?
