SOLIDS: Mass‚ Volume and Density Measurements A. Overview Review Sections 1.4 - 1.6 in your textbook (Chemistry: The Central Science‚ 9th Ed. ‚ Brown‚ LeMay‚ Bursten‚ & Burdge) This experiment will introduce you to a very important concept in science‚ especially chemistry: DENSITY. Density is the relationship between the mass of an object and the volume which it occupies. Solid substances generally have the greatest density‚ normally in the range of 1 - 25 g/cm3. Most liquids have densities between

Gabi Mejia Chem 101 Section ADF Lab 4: Weak Acid Unknown Procedure: When testing the acid‚ use only between 0.2 g and 0.3 g for each trial (get as precise a measurement as you can). The general procedure is to weigh out your acid‚ dissolve it in water‚ add a couple drops of the indicator (phenolphthalein)‚ and then add the sodium hydroxide until you note a color change (from clear to pink). When the color change occurs‚ you have added enough base to completely react with the acid (the endpoint).

Purpose: Cells produce toxic wastes‚ in this experiment hydrogen peroxide‚ and without some sort of molecule to break it down the cell will die‚ along with the organism itself. However with the aid of an enzyme‚ catalase‚ hydrogen peroxide is able to be broken down into an intermediate and thereafter harmless substances water and oxygen. The goal of this lab is to measure the reaction rate of this process in different substances such as a liver‚ a vegetable‚ and breast tissue. By using variables
