Is vinegar or baking soda the independent variable?

What happens when you put an egg in vinegar for 24 hours?

If you soak an egg in vinegar the eggshell will absorb the acid and break down, or dissolve. The calcium carbonate will become carbon dioxide gas, which will go into the air. Soak one egg in vinegar for 24 hours (1 day), one egg for 48 hours (2 days) and one egg for 72 hours (3 days).

What happens when you put an egg in vinegar for 2 days?

2 days later, the outcome is incredible. The egg shell contains calcium carbonate crystals, which are then broken down when interacting with the acetic acid in vinegar. The end-resulting membrane, after the shell dissolves, is also semipermeable and rubbery in texture.

How long does the egg in vinegar experiment take?

It can take 12-24 hours before a good portion of the shell is removed. A good sign of progress is a white frothy scummy layer on the top of the surface of the vinegar. After a day of soaking you can carefully remove the egg from the vinegar.

Does acid weaken eggshell?

When you submerge an egg in vinegar, the shell dissolves, leaving the inner semi-permeable membrane intact. Vinegar (acid) breaks apart the solid calcium carbonate crystals (base) in the eggshell into their calcium and carbonate parts.

How do I make my eggs Clear and squishy?

  1. First get permission to use kitchen equipment and eggs. Then put a raw egg (in its shell) into a bowl and cover it completely with vinegar.
  2. Wait two days, then drain off the vinegar. When you touch the egg, it will feel rubbery. Be careful not to break the membrane, and wash your hands after you touch the egg.

  4. Remove the egg from the glass and rinse it under some tap water.
  5. Examine the egg.

What makes an egg bouncy?

The Science Behind It: The shell of an egg is made of calcium carbonate! When the egg is placed into the vinegar, you see bubbles, which is the chemical reaction of the acid within the vinegar reacting with the calcium carbonate of the egg shell to produce carbon dioxide.

How do you make a bouncy egg with toothpaste?

After the nail polish has dried, place the egg into the measuring cup, marked side down so the Crest toothpaste covers half the egg. Make sure the egg does not touch the bottom of the cup. Cover the cup tightly with plastic wrap and leave it in a safe place at room temperature for at least four full days (96 hours).

What happens if you put an egg in water for 24 hours?

Leave the egg in the water for 24 hours. The water will migrate from the side of the membrane where water molecules are abundant (outside the egg) to the side where water molecules are less abundant. After 24 hours, the egg will be plump again.

When you put an egg in water what happens?

When you put the egg into pure water, some of the water molecules from the solution move into the egg and the egg swells up. You can tell this happens easily if you use food coloring because the egg will change color. You can also observe that the egg is slightly bigger than the untreated egg.

What happens if you put an egg in salt water?

When enough salt is added to the water, the saltwater solution’s density becomes higher than the egg’s, so the egg will then float! The ability of something, like the egg, to float in water or some other liquid is known as buoyancy.
