Question

What will happen if a bone is kept in 10% KOH solution for 3 days?

• A. Remain unchanged
• B. Dissolved
• C. Become soft and elastic
• D. Break

Answer 1

The correct option is A Remain unchanged

Bones are majorly made up of two elements calcium and phosphorus. KOH cannot demineralize the calcium. Thus, bone-in KOH remain unaffected. But, the surrounding muscles and connective tissue get dissolved, so that the bone now appears clean.
So, the correct answer is (A) - remains unchanged.
