Vinegar is primarily made up of acetic acid. Acetic acid (or ethanoic acid) is a two-carbon carboxylic acid. It's formula is CH3COOH. It has a methyl group attached to a carbonyl carbon that is also attached to a hydroxyl group.
Vinegar is a solution of acetic acid in water.
Acetic acid: CH3COOH.
Oil is more dense than vinegar. Oil has a higher density due to its molecular composition and structure, which makes it less buoyant and more likely to sink in vinegar.
Vinegar (acetic acid) can dissolve diamonds that have been chemically treated or have impurities on their surface. However, natural diamonds, which are pure carbon and have a strong crystal structure, are not affected by vinegar and cannot be dissolved by it.
When you mix sand and vinegar, the vinegar will dissolve any minerals in the sand, causing it to clump together or form a sludge-like mixture. This is because the acetic acid in the vinegar reacts with the minerals in the sand, breaking down their structure.

Vinegar (as bought in your grocery store) is about 96% water. Salt dissolves rapidly in it.
Vinegar should decalcify the bones. I.E. The bones are made out of mainly calcium carbonate. The vinegar will break it down. There are other compounds in the bones that will remain so the bones will seem soft.
When vinegar is spotted onto chalk or limestone, it creates a chemical reaction that dissolves the calcium carbonate in the rock. This reaction is not reversible as it breaks down the structure of the rock and changes it permanently.
The question for the Bouncy Egg Project could be: "How does soaking an egg in vinegar affect its structure and ability to bounce?"
No. Adding vinegar to water is a physical process. You are making a vinegar solution, and the chemical structure of both the water and the vinegar does not change. You can physically separate the vinegar from the water through the physical process of distillation.
Vinegar is commonly used to make chicken bones more flexible due to its acidity, which helps break down the bone material. Placing a chicken bone in vinegar for a few hours or days can weaken the bone structure, making it more flexible.
