Vinegar Vs Water Lab

Vinegar versus Water Solutions

Purpose:To see what will happen when we put an egg in vinegar versus an egg in water.

Hypothesis:I think the egg in vinegar will harden, and I think the egg in water will have no effect to the egg.

Materials\Apparatus:

- 2 large eggs

- 2 400ml glass beakers

- 250ml of water

- 250ml of white vinegar

- Flexible measuring tape

- Triple beam balance

- Spoon

Method:

1.Measure both eggs.

2.Fill beaker #1 with 250ml of water and then place egg #1 in beaker.

3.Fill beaker #2 with 250ml of vinegar and then place egg #2 in beaker.

4.Wait 48 hours for the results.

5.After 48 hours, drain liquid and take the egg out with a spoon and rinse.

6.Remeasure both eggs and compare to old data

Observations:Day #1

Quantitative:Egg #1: Length:16.6cm Width:14.5cm Weight:67.1g Egg #2: Length:16.3cm Width:14.3cm Weight:64.0g

Egg #1: Qualitative

- The liquid went up 300ml after putting

I was partially right because the egg became a solid, but the inside is still liquid. But I was right about the egg in water because nothing really changed. This experiment worked because the eggs are made of calcium carbonate also the vinegar has acetate in it. The chemical reaction reduced the carbon dioxide furthermore the egg shell dissolved. The egg shell was permeable. But the water from the vinegar went through the egg through osmosis. The egg membrane is semipermeable because it did not let the water get through and kept the egg a solid. Some sources of error might of happened. The scale might of been defective and the measuring tape would have been in the wrong spot when remeasuring. The beakers were beside a sink so the water may have splashed in the beaker. Some of these sources of error could have changed the way our eggs became later. Overall this was a really Egg-straordinary
