What happens if bone of frog is kept in dilute hydrochloric acid :
A
Will become flexible
B
Will turn black
C
Will break in pieces
D
Will shrink
Detailed Solution
Bone consists of an organic matrix (mainly the protein ossein/collagen) hardened by inorganic salts, chiefly calcium phosphate and calcium carbonate.
Dilute HCl dissolves the calcium salts (decalcification), leaving only the organic matrix.
Without the minerals, the bone keeps its shape but becomes soft and flexible (it can even be tied in a knot).
So the bone will become flexible.
