Bone becomes moist when kept in dilute hydrochloric acid, why?
​

Answer 1

Answer:

Explanation:Bone becomes brittle and more susceptible to brekage  but it doesnot melt because their are other minerals such as K, vitaman that makes up the bone. when a bone is dipped into hcl medium, the calcium of bone slowly starts to dissolve due to  action of strong acid.

HCl+Ca=CaCl2+H2
