Question

Egg shells are largely made
of calcium carbonate.
Predict what will happen if
you add some vinegar to an
egg with its shell on. Explain
your prediction. Carry out
the experiment and observe.
Was your prediction correct?​

Answer 1

Explanation:

Vinegar has, among other things, a chemical called acetic acid (about 3% of it is acetic acid). 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).
