I would imagine that it often neutralises the pH of the vinegar
The bone will lose some of its calcium and be slightly more flexible.
Put an egg in vinegar and the base calcium of the eggshell will be dissolved by the acid of the vinegar.
You put the seashells in a cup of vinegar
The acid in the vinegar dissolves out the calcium in the chicken bone. (Calcium is most of the reason that bones are hard.)
poops the vinegar
When you put chalk in vinegar the chalk is dissolved and broken down. However, as a result of the mixture of compounds co2 is formed.
It melts
nothing happens
Vinegar dissolves the eggshell. Vinegar contains a chemical named Acetic Acid (about 3% of it is acetic acid), among other things. Egg shells contain calcium carbonate. Calcium carbonate in the egg shell reacts with vinegar to form carbon dioxide (can be seen as bubbles in the vinegar). The reaction is: CaCO3+ 2H+ -> Ca+2 + H2O +CO2
Jade is not soluble in vinegar.
because it has calcium in it and if u put it in vinegar it will become bendable after a few days
the celery will die
