Answer 1

⠀⠀ ⠀ ⠀⠀ $\huge{\tt{\red{❥}\green{A}\purple{N}\pink{S}\blue{W}\orange{E}\red{R}}}$HCl is hydrochloric acid, strong acid. Bone is made of minerals, and the most prominent mineral is calcium. When a bone is dropped in the HCl medium, the calcium of bone slowly starts dissolve due to the action of the strong acid. HCl + Ca -> CaCl2 + H2. Afterward, the bone is depleted of calcium but it does not "melt" because there are other minerals that make up the bone such as potassium, vitamins, and collagen. Since calcium is the main mineral in the bone, the bone becomes brittle and more susceptible to breakage
