Is the egg experiment osmosis or diffusion?
Is the egg experiment osmosis or diffusion?
Osmosis will occur; that is, the water will migrate from the side of the membrane where water molecules are abundant (i.e. outside the egg) to the side where water molecules are less abundant (inside the egg). After 24 hours, the egg will be plump again! Experiment with naked eggs by soaking them in other solutions.
What is the conclusion of the egg osmosis lab?
Discussion and Conclusion: While two of the solutions caused the eggs to increase in mass, syrup caused the egg to lose mass. This shows that the syrup was hypertonic to the solution inside of the egg, causing water to diffuse out of the egg to try and establish equilibrium.
How is diffusion shown in egg experiment?
(The movement of water across a membrane is a special version of diffusion called osmosis.) When an egg is soaked in a solution in which the concentration of water is higher than that inside the egg, water moves from the outside solution, across the membrane and into the egg.
What is the purpose of the egg diffusion lab?
Egg diffusion experiments reveal an animal cell’s ability to block certain materials and allow others, particularly oxygen and nutrients, to enter using the process of diffusion.
What happens when you put an egg in salt water osmosis?
Water moves by osmosis from a weak (dilute) solution to a strong (concentrated) solution, such as the solution inside the egg. So when you put an egg in water only, water flows in through the membrane making the egg expand. The egg in the salt water shrunk.
At what point was the egg in a hypertonic solution explain what happened in this process?
In the case of the hypertonic solution, there were more solutes in the corn syrup than there were in the egg. So, water flowed out of the egg and into the corn syrup, and as a result the egg shriveled up.
What is the independent variable in the egg osmosis lab?
1) The independent variables were the types of solution used to soak the egg in. They are corn syrup and tap water. The dependent variables were the circumference and mass of the egg after being put into each solution. 2) The control group was the egg in vinegar, which is the isotonic solution.
What is the conclusion of an egg floating in water?
An egg floats in salt water because the mass of the salt water displaced is equal to the mass of the egg. The egg’s density is less than the density of the salt water. When an egg is placed in fresh water it immediately sinks to the bottom of the container it is placed in.
What happen to the egg that is placed in a hypotonic solution conclusions?
In the case of the hypotonic solution, there were more solutes in the egg than in the pure water. So, water flowed into the egg, and as a result, it grew in size.
What is the hypothesis of an egg in a vinegar?
* An egg shell is selectivley permeable, meaning that an egg shell has many tiny microscopic holes in it, allowing the vinegar to pass through it. Hypothesis: If we placed an egg in vinegar, Then it’s shell will dissolve and The egg will Become Bouncy.
What is the dependent variable in the egg and vinegar experiment?
The independent variable is the vinegar and the dependent variable is the egg. We believed that the egg would be softer; because we saw the vinegar bubble once we put the egg in it.
What are the variables in the egg experiment?
1. The independent variables were the different solutions we put the I.V. egg in — the corn syrup, the water, and the vinegar. The dependent variables were the mass and circumference of the egg after each day, telling us whether the egg grew or shrank.
What is the independent variable in the floating egg experiment?
The independent variable was adding salt to the water. The dependent variable was the egg floating in the water.
Why do you think one egg sinks and the other egg floats?
Materials that are less dense than the liquid they are in will float. For example, an egg floats in salt water because the egg is less dense than the salt water. On the other hand, if an egg is placed in fresh water it sinks to the bottom immediately because the fresh water is less dense.
What happens when an egg is placed in a hypertonic solution?
A concentrated sugar solution is hypertonic compared to the solution inside the egg. Therefore when the egg is placed in the concentrated sugar solution water flows out of the egg, causing it to shrivel.
What is the independent variable in the egg experiment?
Before letting the egg submerge in vinegar overnight the initial weight of the egg was 66.6 grams. We thought that after leaving the egg in vinegar the shell of the egg would get softer. The independent variable is the vinegar and the dependent variable is the egg.
What is the dependent variable in the egg osmosis lab?
Is an egg influenced by osmosis and diffusion?
Those bubbles are caused by CO2 escaping. As the egg now only has a membrane covering it, molecules can diffuse in and out. When the egg is placed in honey or corn syrup, the egg will loose most of its water. This is because there is a higher concentration of water molecules inside the side than outside the egg.
What is the purpose of the egg osmosis lab?
Egg Osmosis Lab. Purpose: The purpose of this lab is to demonstrate what happens when an animal cell is exposed to varying osmotic environments. Questions to Think About: What happens when a cell is subjected to a solution where the water concentration is higher than that inside a cell (hypotonic solution)?
What is the end result of diffusion or osmosis?
Diffusion
What are some similarities and differences between osmosis and diffusion?
Occurs in any mixture or media.
