Objective: To observe the effects of osmosis on eggs placed in vinegar (5% acetic acid)‚ syrup (60% sugar solution)‚ and water (100% distilled). Hypothesis: Hypothesis #1: It was hypothesised that the egg would gain 59 grams of mass after soaking in vinegar for 24 hours. Hypothesis #2: It was hypothesised that the egg would become larger when soaked in syrup than it once was due to the hypotonic environment. Hypothesis #3: It was hypothesised that the egg would soak in water for 72 hours‚ losing mass

what happens to a fresh egg when osmosis and diffusion across membranes. The eggs were placed in vinegar‚ distilled water‚ and then lastly syrup. The eggs were weighed every day to see if they got heavier or lighter. My hypothesis is that the eggs will absorb the contents it’s placed in and will become heavier. First‚ the fresh hen’s eggs were placed in vinegar. On March 10th‚ 12 eggs were placed

Can salt change water’s density? I conducted an experiment using common household items to find an answer to my question. The procedure involves filling two cups with two hundred fifty milliliters of water. Then‚ mixing teaspoons of salt in water one at a time‚ until you’re able to submerge a raw egg in the solution and have it float up. My hypothesis is‚ salt does infact change water’s density‚ and if the egg floats it’s proof of density change in the water‚ because it must be less dense than the

Daniel H. Perry Procedures of Measurement and Density of Sugar in Soda Introduction The main focus of this lab was to acquire a basic understanding of how 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

Why do boats float? All boats float‚ but floating is harder and confusing than it sounds and its best explained through a scientific concept called buoyancy. Buoyancy is the force that causes floating. An object will either float or sink depending on its density in the water. If it’s denser than water‚ it mostly sinks; the less dense object usually will float. It doesn’t matter the size of the object is. Plastic that is big as a football field will float because it is less dense that the water. A
