1Most common and very rapid decalcifying agent
[blank_start]Nitric acid[blank_end]- ANitric acid
2The endpoint of decalcification of nitric acid must be carefully watched for to prevent progressive tissue damage and impaired staining
It may be prevented by combining nitric acid with [blank_start]Formaldehyde[blank_end] or [blank_start]Alcohol[blank_end]- AFormaldehyde
- BAlcohol
3It is recommended for urgent biopsy, needle and small biopsy specimens to permit rapid diagnosis within 24 hours or less. Its decalcification time is 12 to 24 hours

Its decalcification time is 1 to 3 days
[blank_start]Formol[blank_end]-[blank_start]nitric[blank_end] [blank_start]acid[blank_end]- AFormol
- Bnitric
- Cacid
5The yellow color caused by formol-nitric acid can be prevented by:
