Sardines are cooked at up to 240deg F during the canning process which makes the bones soft.
When you put a chicken bone in vinegar, a chemical reaction occurs due to the acidic nature of vinegar. The acetic acid in the vinegar breaks down the calcium in the bone, which is a key component of bone structure. Over time, the bone will start to soften and eventually dissolve as the calcium is leached out into the vinegar solution. This process is known as demineralization and is often used in educational settings to demonstrate the effects of acids on calcium-based materials.
Fish bone can be softened by leaving the opened fish in vinegar. However, the backbones which you see when you open a tin of salmon are made soft by the cooking method, which is similar to pressure-cooking.
Since marble is made primary of calcium carbonate which when mixed with vinegar reacts like this CaCO3 + 2 CH3COOH --> Ca(CH3COO)2 + H2O + CO2 the vinegar turns the marble into water and carbon dioxide. if you ever herd of eggshells dissolving in vinegar there made out of the same stuff marble is made out of.
The vinegar makes the egg soft because, the vinegar has a chemical reaction due to the Carbon Dioxide in the vinegar which has an effect on the egg. That's why the egg's shell dissolves off, and the egg gets soft.
The combination of vinegar and heat causes the calcium and collagen in the bone to break down. this makes the bone flexible and spongy like cartilage. the purpose of the experiment is to help you understand the difference between bone and cartilage and why they are different. The experiment should also be done with two separate chicken bones - one soaked in vinegar which breaks down the calcium leaving it flexible or rubbery; the other is baked which destroys the collagen leaving it brittle.
Yes, I'm sure adding vinegar makes the bones release calcium because I make chicken stock with bones a lot, and when I add vinegar, the stock turns white. After I remove the bones, sometimes I eat them, and they are really soft after they cook for a long time with vinegar in the water. I just eat the soft part on the ends of the bones. Chicken stock made with bones is fantastic, I love it. Bones are great in stock.
It depends upon the acid.A strong acid will easily dissolve the bone while a weak one won't.I think HCL to be a strong acid so the bone will be dissolved in it.
The vinegar makes the egg soft because, the vinegar has a chemical reaction due to the Carbon Dioxide in the vinegar which has an effect on the egg. That's why the egg's shell dissolves off, and the egg gets soft.Correction:A raw egg will NOT bounce when dropped into vinegar. The egg must sit in vinegar for about 24 hours, so that the vinegar will react with the carbon dioxide in the egg shell, before the egg will become soft and rubbery. See link below.
No, the bone-in skinless chicken breast is a slightly more healthy choice because of the white "soft bone" that is edible and rich in calcium. Bone-in chicken does take a longer time to cook fully, but also gives better flavour.
Becasue chicken is soft
When a chicken bone is soaked in cola, the acidic nature of the cola can weaken the bone structure. Over time, the cola can dissolve some of the calcium and minerals in the bone, causing it to become softer and potentially break down.
