How do you dissolve fish bone?

To dissolve fish bones, you can use an acidic solution, such as vinegar or lemon juice. Soaking the bones in these acids can help break down the calcium carbonate that makes up the bones. Heating the solution can speed up the process, but it's essential to monitor it closely to avoid overcooking. However, it's important to note that this method is more effective for softening bones rather than completely dissolving them.
