to properly use measuring devices in order to determine properties of a liquid. These properties are volume‚ mass‚ and density. The following measurements were obtained in the lab: density of water‚ both density and concentration of aqueous sugar solutions‚ and density of various soft drinks with respect to sugar. Additional experience was obtained by using specific formulas to accurately calculate percent error and percentage of sugar in different sodas. Lastly‚ familiarity with graphing aspects of

proteins. We used a raw egg and noted the changes that happen when there were changes in temperature‚ pH levels‚ and salinity. Five eggs were cracked open and placed into different bowls with different solutions placed into each bowl. What we looked at was the process of denaturing of proteins seeing how it affected the composition of the raw egg between the yoke and white portion. My hypothesis for this experiment is: Solution 1 will case the egg to denature and separate‚ Solution 2 will stay original

The Floating Egg Problem Introduction: This experiment was constructed to aid in the practice of using the volumetric system and the glassware that determines volume. Volumetric glassware contains an accurate amount of liquid and also measures the volume accurately. Density is a measure of how much matter takes up a certain amount of space or volume. The more matter you can pack into a certain space‚ the denser it is. Although we often confused the two‚ density and weight are actually two

Are naked eggs with no shell? What? You may think I am speaking about a hard boiled egg‚ but‚ no. Boiled eggs have their centers heated making the shell easily come off. Naked eggs have their shells taken off with one simple ingredient everyone has. Vinegar. The vinegar acid inside the vinegar strips the shell away from the egg. The vinegar solutions dissolves the shell from the egg. Once the egg has been separated form it’s shell the only thing keeping the liquid goo inside is the thin‚ flexible
