Transcript of The Effects of Water and Vinegar on Egg Shells

The Effects of Water and Vinegar on Egg Shells
Data table/ observations
Procedure
1) Fill one Mason jar completely full of distilled white vinegar.
2) Fill another Mason jar completely full of water.
3) Fill your third jar with 3/4 water and 1/4 distilled white vinegar.
4) Fill your fourth jar with 1/2 water and 1/2 vinegar.
5) Fill your fifth and final jar with 3/4 distilled white vinegar and 1/4 water.
6) Gently drop each egg into jars. The eggs should fizz.
7) Make observations about each egg over 2 days. Find out which liquid dissolves the egg shell first. Then turn your results into a data table.
Purpose/Problem
To understand what happens to hard-boiled egg shells when placed in vinegar, water, and different mixtures of vinegar and water over a period of days. You want to find out which liquid will dissolve your egg shells first.
Hypothesis
If I place 5 hard-boiled eggs with their shells in different mixtures of vinegar and water, I think the pure vinegar will dissolve the egg shell first because vinegar has the highest acid content.

Some of the eggs move, either to the top of jar or roll over in the jar. 80% of the eggs have done something like moving, but only 20% of the eggs have lost any of its shell
On day 2 the eggs didn’t move at all, only the shells started to dissolve. Vinegar is the liquid that dissolves the egg shells the fastest. The water egg shell didn’t dissolve at all. That proves my hypothesis correct, if I place 5 hard-boiled eggs with their shells in different mixtures of vinegar and water, I think the pure vinegar will dissolve the egg shell first because vinegar has the higher acid content.
In this experiment, I wanted to find out what would happen to hard- boiled eggs if placed in different mixture of vinegar and water, which liquid would dissolve the shell first. The vinegar from the very beginning seemed it would dissolve the egg shell the fastest. This compared to the egg placed in water (this egg didn’t dissolve whatsoever) showed greater signs of dissolving faster. There were trends with the eggs with the mixtures of vinegar and water, since they all dissolved the shells about the same time. I will accept my hypothesis since my hypothesis was, if I place 5 hard-boiled eggs with their shells in different mixtures of vinegar and water, I think the pure vinegar will dissolve the egg first because vinegar has the higher acid count. That was exactly what happened in my experiment. I learned that vinegar is an acid and water isn’t because the reason the egg shells dissolved is from the vinegar. This was a fair test because the eggs were the same size, so were the jars and the water/vinegar amounts were all the same. If I were to continue this experiment I would leave the eggs in the mixtures longer and see if the vinegar would start to dissolve the real egg.
