The ingredient of the fixing solution of the X-ray is
1) Hydroquinone
2) Elon
3) Sodium bisulphate
4) Acetic acid
Radiology
Answer: 4
Acetic acid is a key ingredient in the fixing solution used in radiography. It acts as a stop bath, neutralizing the developer and maintaining the acidic environment necessary for proper fixation. Hydroquinone and elon are developer agents, while sodium bisulfate is not typically part of the fixing process.
