Question
A piece of bone such as femur of frog if kept in dilute HCl for about a week will
Options
A.assume black colour
B.shrink in size
C.turn flexible
D.crack into pieces
Solution
When a bone is kept in dilute acid for a few days, the salts get dissolved leaving only soft and flexible organic matrix (decalcification). If kept in KOH, it remains unaffected, only the sur rounding muscles and connective tissue get dissolved so that the bone now appears clean. If burns, the organic matter burns off producing smoke and the ash (mineral matter) is left behind.
