Which solutions were isotonis to the egg?
15% @%% 30% 40% 50%
To determine which solutions are isotonic to the egg, we need to understand the concept of isotonicity.
An isotonic solution is one that has the same concentration of solutes as the solution it is being compared to. In this case, we are comparing the solutions to the egg, so we want to find the concentration of solutes in the egg.
To figure out the concentration of solutes in the egg, we can use a process called egg osmosis. Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.
To conduct the egg osmosis experiment, you will need:
1. Several eggs
2. A beaker or container for each solution
3. Solutions with different concentrations (15%, 30%, 40%, 50%)
4. Water
Here's how you can conduct the experiment:
1. Start by carefully placing each egg in its own beaker or container.
2. Label each beaker with the concentration of the solution it contains.
3. Fill each beaker with enough of the respective solutions to completely cover the eggs.
4. Leave one beaker empty, which will serve as the control group.
5. Fill another beaker with water, which will be used to determine the concentration of solutes in the egg.
6. Let the eggs soak in the solutions for a specific amount of time, usually 24 hours. Make sure to keep track of the time.
7. After 24 hours, carefully remove each egg from its beaker, dry it gently with a paper towel, and record its observations. Pay attention to changes in size, texture, and color.
8. Compare the appearance of the eggs in the different solutions to the control group.
9. The solution that results in an egg with no significant changes in size, texture, or color is the isotonic solution.
By conducting this experiment, you can determine which of the given solutions (15%, 30%, 40%, or 50%) is isotonic to the egg.
